[0007]Further, the invention is concerned with a process for the
manufacture of the above compounds, pharmaceutical preparations which
contain such compounds as well as the use of these compounds for the
production of pharmaceutical preparations.
[0008]The compounds of formula (I) are compounds that inhibit the activity
of coagulation factor Xa. These compounds consequently influence blood
coagulation. They therefore inhibit the formation of thrombi and can be
used for the treatment and/or prevention of thrombotic disorders, such as
amongst others, arterial and venous thrombosis, deep vein thrombosis,
peripheral arterial occlusive disease (PAOD), unstable angina pectoris,
myocardial infarction, coronary artery disease, pulmonary embolism,
stroke (cerebral thrombosis) due to atrial fibrillation, inflammation and
arteriosclerosis. They can also be used in the treatment of acute vessel
closure associated with thrombolytic therapy and restenosis, e.g. after
transluminal coronary angioplasty (PTCA) or bypass grafting of the
coronary or peripheral arteries and in the maintenance of vascular access
patency in long term hemodialysis patients. Factor Xa inhibitors of this
invention may form part of a combination therapy with an anticoagulant
with a different mode of action or with a platelet aggregation inhibitor
or with a thrombolytic agent. Furthermore, these compounds have an effect
on tumor cells and prevent metastases. They can therefore also be used as
antitumor agents.
[0009]Other inhibitors of factor Xa, which are not structurally related to
the compounds of the present invention, had previously been suggested for
the inhibition of the formation of thrombi and for the treatment of
related diseases (WO 03/045912). However, there is still a need for novel
factor Xa inhibitors which exhibit improved pharmacological properties,
e.g. an improved selectivity towards coagulation factor Xa.
[0010]The present invention provides the novel compounds of formula (I)
which are factor Xa inhibitors, intermediates for the synthesis of
compounds of formula (I), and methods of using compounds of formula (I).
The compounds of the present invention unexpectedly inhibit coagulation
factor Xa and also exhibit improved pharmacological properties compared
to other compounds already known in the art.

given above are those specifically exemplified in Examples.
[0030]Compounds of formula (I) can form pharmaceutically acceptable acid
addition salts. Examples of such pharmaceutically acceptable salts are
salts of compounds of formula (I) with physiologically compatible mineral
acids, such as hydrochloric acid, sulphuric acid, sulphurous acid or
phosphoric acid; or with organic acids, such as methanesulphonic acid,
p-toluenesulphonic acid, acetic acid, lactic acid, trifluoroacetic acid,
citric acid, fumaric acid, maleic acid, tartaric acid, succinic acid or
salicylic acid. The term "pharmaceutically acceptable salts" refers to
such salts. Compounds of formula (I) in which a COOH group is present can
further form salts with bases. Examples of such salts are alkaline,
earth-alkaline and ammonium salts such as e.g. Na--, K--, Ca-- and
Trimethylammoniumsalt. The term "pharmaceutically acceptable salts" also
refers to such salts. Acid addition salts as described above are
preferred.
[0031]"Leaving group" has the meaning conventionally associated with it in
synthetic organic chemistry, i.e., an atom or a group capable of being
displaced by a nucleophile and includes halo (such as chloro, bromo, and
iodo), alkanesulfonyloxy, arenesulfonyloxy, alkylcarbonyloxy (e.g.,
acetoxy), arylcarbonyloxy, mesyloxy, tosyloxy,
trifluoromethanesulfonyloxy, aryloxy (e.g., 2,4-dinitrophenoxy), methoxy,
N,O-dimethylhydroxylamino.
[0032]"Enantiomerically pure" means that the enantiomeric excess exceeds
95%.
[0033]"Optional" or "optionally" means that the subsequently described
event or circumstance may but need not occur, and that the description
includes instances where the event or circumstance occurs and instances
in which it does not. For example, "aryl group optionally substituted
with an alkyl group" means that the alkyl may but need not be present,
and the description includes situations where the aryl group is
substituted with an alkyl group and situations where the aryl group is
not substituted with the alkyl group.
[0034]"Pharmaceutically acceptable excipient" means an excipient that is
useful in preparing a pharmaceutical composition that is generally safe,
non-toxic and neither biologically nor otherwise undesirable, and
includes excipient that is acceptable for veterinary use as well as human
pharmaceutical use. A "pharmaceutically acceptable excipient" as used in
the specification and claims includes both one and more than one such
excipient.
[0035]Compounds that have the same molecular Formula but differ in the
nature or sequence of bonding of their atoms or the arrangement of their
atoms in space are termed "isomers." Isomers that differ in the
arrangement of their atoms in space are termed "stereoisomers".
Stereoisomers that are not mirror images of one another are termed
"diastereomers" and those that are non-superimposable mirror images of
each other are termed "enantiomers". When a compound has an asymmetric
center, for example, if a carbon atom is bonded to four different groups,
a pair of enantiomers is possible. An enantiomer can be characterized by
the absolute configuration of its asymmetric center and is described by
the R- and S-sequencing rules of Cahn, Ingold and Prelog, or by the
manner in which the molecule rotates the plane of polarized light and
designated as dextrorotatory or levorotatory (i.e., as (+) or (-)-isomers
respectively). A chiral compound can exist as either individual
enantiomer or as a mixture thereof. A mixture containing equal
proportions of the enantiomers is called a "racemic mixture".
[0036]The compounds of formula (I) wherein E is E-1 or E-2 have at least
two asymmetric centers on the adjacent carbon atoms belonging to a
cyclopentane or cyclopropane ring. Thus, they can therefore exist as a
diastereomeric mixture of trans and cis compounds, or as a pure trans
compounds or a pure cis compounds. Moreover, each of trans and cis
compounds can exist as an enantiomeric mixture or as optically pure
compounds. The compounds of this invention wherein E is E-3 can possess
one or more asymmetric centers. Unless indicated otherwise, the
description or naming of a particular compound in the specification and
claims is intended to include both individual enantiomers and mixtures,
racemic or otherwise, thereof. The methods for the determination of
stereochemistry and the separation of stereoisomers are well-known in the
art (see discussion in Chapter 4 of "Advanced Organic Chemistry", 4th
edition J. March, John Wiley and Sons, New York, 1992).
[0037]Thus, the invention provides novel dicarboxamide derivatives of the
formula (I)

a) Synthesis of Key Intermediates Trans- and Cis-Ketones and Epoxides
##STR00019##
[0164]The mono saponification of methylene-cyclopentane-1,2-dicarboxylic
acid diethyl ester (available by the method described by B. M. Trost et
al., J. Am. Chem. Soc., 105, 2315, 1983) can be effected by dissolving it
in a suitable solvent like MeOH, EtOH, THF, 1,4-dioxane, water or
mixtures thereof and a base like LiOH, NaOH, KOH, Na.sub.2CO.sub.3,
K.sub.2CO.sub.3 or Cs.sub.2CO.sub.3, preferably MeOH and K.sub.2CO.sub.3.
[0165]The mono acid is dissolved in a suitable solvent like
dichloromethane, DMF, acetonitrile, THF, NMP, DMA, etc. and activated
with an amide coupling reagent like EDC, DIC, DCC, CDI, TBTU, HBTU, EEDQ,
HOBt, HATU, PyBOP, PyBrOP, BOP, BOP-Cl, etc. in the presence of a base
like NEt.sub.3, hunigs base, N-methylmorpholine etc. at -20.degree. C. to
120.degree. C. By adding one to two equivalents of the amine D-NH.sub.2
the corresponding monoamide is obtained after reaction for 0.5-120 h at
-20.degree. C. to 120.degree. C. Alternatively, transformation of the
acid into the corresponding acid chloride or anhydride by means of oxalyl
chloride, thionylchloride, isobutylcarbamoyl chloride or related reagents
and a base like NEt.sub.3, hunigs base, N-methylmorpholine etc, and
reaction with D-NH.sub.2 (all D-NH.sub.2 commercially available) yields
also the corresponding monoamide. The preferred conditions involve THF,
EDC, HOBt and NEt.sub.3.
[0166]Saponification of the ester group can be effected as described
above. The second amide group can be introduced as described above using
R.sup.c--B--NH.sub.2, the preferred method involves isobutylcarbamoyl
chloride as activating agent and N-methylmorpholine as base at -20 to
60.degree. C. The trans- and cis-isomers can be separated by
chromatography on silica.
[0167]Preparation of the aniline derivative R.sup.c--B--NH.sub.2 can be
carried out according to the method described by C. F. Bigge et al.
(patent application WO 2003045912).
[0168]Conversion of the olefine to the ketone group by periodate cleavage
can be accomplished under standard conditions using OSO.sub.4 and
NaIO.sub.4 in a solvent like an alcohol e.g. MeOH and water at 0.degree.
to 70.degree. C. preferably at 20.degree. C. for 1 to 20 h.
[0169]Epoxidation of the olefine can be accomplished with an oxidizing
agent such as peracids, e.g. MeCOOOH or MCPBA in a solvent like e.g.
CH.sub.2Cl.sub.2 at 0 to 50.degree. C., preferably at 20.degree. C. to
give a mixture of epimers which can be separated by chromatography on
silica.
b) Modifications of the Trans- and Cis-Ketones
##STR00020##
[0171]G in the scheme is mono or di-substituted amino as defined before.
Reductive amination of the ketone with HG (all bases commercially

preferably CH.sub.3COOH at a temperature of -10 to 60.degree. C.,
preferably at 20.degree. C. for 1-40 h. The products obtained consist of
a mixture of epimers at the newly formed stereo center.
[0172]Acylation and sulfonylation can be performed by reaction of the
amine with a chloroformate, nitrophenylformate or a sulfochloride in the
presence of a base, e.g. NEt.sub.3 or preferably
N,N-diisopropylethylamine in a solvent such as e.g. THF, CH.sub.2Cl.sub.2
or preferably CH.sub.3CN at -10 to 60.degree. C., preferably at
20.degree. C. for 1-40 h. The products obtained consist of a mixture of
epimers at the G stereo center.
[0173]Reduction of the ketone to the alcohol can be effected by reducing
agents e.g. Li(CN)BH.sub.3, Na(CN)BH.sub.3, LiBH.sub.4 or preferably
NaBH.sub.4 in a solvent such as e.g. MeOH or preferably THF at a
temperature of -10 to 60.degree. C., preferably at 20.degree. C. for 1-40

R'.sup.3OH as the solvent at 0 to 100.degree. C., preferably at
20.degree. C. for 1 to 40 h. The products obtained consist of a mixture
of epimers at the alcohol stereo center.
[0178]Ring-expansion of the epoxide can be accomplished with
2-chloroethanol as R.sup.13OH in the presence of BF.sub.3.OEt.sub.2 as
described above followed by cyclization of the intermediate chloroalcohol
using KI as activating agent and a strong base such as LiOH, NaOH, KOH,
preferably NaOH in a solvent mixture of CH.sub.3CN and water at 50 to
150.degree. C. in a microwave apparatus. The products obtained consist of
a mixture of epimers at the ether stereo center.
[0179]Reductive ring-opening of the epoxide can be effected according to
A. Heydari et al. (Synthesis, 10, 1563, 2004) with a reducing agent such
as BH.sub.3 or preferably BH.sub.3.NEt.sub.3 in the presence of a
promoter such as LiClO.sub.4 in Et.sub.2O as the solvent at 0 to
50.degree. C., preferably at 20.degree. C. for 1-40 h. The products
obtained consist of a mixture of epimers at the alcohol stereo center.
d) Modifications of the Amide Group
##STR00022##
[0181]G in the scheme is mono or di-substituted amino as defined before.
[0182]Curtius rearrangement (step i) of
methylene-cyclopentane-1,2-dicarboxylic acid ethyl ester to the
t-butyloxycarbonyl protected amine was accomplished with
diphenylphosphoryl azide and an amine, e.g. NEt.sub.3 in a solvent such
as benzene or preferably toluene at 20 to 150.degree. C., preferably at
80.degree. C. for 1-40 h. The intermediate isocyanate can be trapped with
an alcohol such as MeOH, EtOH or preferably t-BuOH at 20 to 150.degree.
C., preferably at 80 to 90.degree. C.
[0183]Saponification (step ii) and amide formation (step iii) can be
accomplished as described in the synthetic procedure 1a).
[0184]Deprotection (step iv) can be effected with a mineral acid such as
HCl, H.sub.2SO.sub.4 or H.sub.3PO.sub.4 or a carbonic acid, preferably
CF.sub.3COOH in a solvent such as CH.sub.2Cl.sub.2 at 0 to 60.degree. C.,
preferably at 20.degree. C. for 1-40 h.
[0185]Amide formation (step v) using R.sup.c--B--COOH, which can be
prepared according to the method described by C. F. Bigge et al. (patent
application WO 2003045912) and steps vi-ix can be carried out as
described in the synthetic procedures 1a) and 1b). The products obtained
consist of a mixture of epimers at the newly formed stereo center.
[0186]Et in the schemes under procedure 1.a) to d) can be replaced with
another C.sub.1-6 alkyl group, preferably C.sub.1-4 alkyl group. B,
R.sup.c and D in the schemes under procedure I.a) to d) are as defined
before. D is preferably 4-chloro phenyl. --B--R.sup.c is preferably
2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenyl.
2. Synthesis of Cyclopentane Dicarboxamide Derivatives (Homochiral)
a) Synthesis of Key Intermediates Trans-Ketones and Epoxides
##STR00023##
[0188]The resolution of racemic
trans-methylene-cyclopentane-1,2-dicarboxylic acid diethyl ester via mono
saponification can be accomplished with lipase PN from Phycomyces nitens
to afford the enantiomerically pure S,S-diethyl ester as retained
enantiomer.
[0189]The following selective mono saponification with lipase OF from
Candida rugosa delivered the enantiomerically pure S,S-monoethyl ester.
The used hydrolases were selected from a set of selective ones (like e.g.
lipase G from Penicilium camenberti, lipase N from Rhizopus niveus or
lipase PN from Phycomyces nitens) and active ones (like e.g. lipase OF
from Candida rugosa, lipase RMM from Rhizomucor miehei, esterase PLE from
pig liver or protease Subtilisin A from Bacillus licheniformis)
discovered in a library out of 118 commercially available enzymes.
Interestingly, the esterase from pig liver, which was used in a
resolution of racemic trans-4-oxo-cyclopentane-1,2-dicarboxylic acid
diethyl ester published by A. Rosenquist et al. (Acta Chem. Scan., 46,
1127, 1992), turned out to be not enantioselective for the resolution of
racemic trans-methylene-cyclopentane-1,2-dicarboxylic acid diethyl ester.
[0190]Both enzymatic hydrolysis steps were performed as emulsion of the
substrates in an aqueous buffer system. During the reaction the selected
pH-value was maintained by controlled addition of a base. The selectivity
and/or activity could be influenced by the addition of salts or organic
solvents or by lowering the reaction temperature as shown in the
preparative example. The work up of the products was achieved by
conventional extractive procedures with different organic solvents at a
proper pH-value.
[0191]Conversion of the mono acid to the ketone and epoxide epimers can be
carried out as described in the synthetic procedures 1a)
b) Modifications of the Epoxide and Olefine
##STR00024##
[0193]Ring opening of the epoxide can be effected as described in the
synthetic procedure 1c). Both epimers are available as single isomer.
[0194]Cyclopropanation of the olefine can be carried out according to the
method described by H. E. Simmons and R. D. Smith (J. Am. Chem. Soc. 80,
5323, 1958) involving diethylzinc, CH.sub.2I.sub.2 and trifluoroacetic
acid in a solvent such as toluene or CH.sub.2Cl.sub.2 or a mixture
thereof.
c) Modifications of the Intermediate Keto- and Hydroxyl-Esters
##STR00025##
[0196]In a different strategy, modifications of the keto- and
hydroxyl-group can be effected prior to the introduction of --B--R.sup.c,
since e.g. the intermediate epimers of the hydroxyester (only one epimer
depicted in the scheme) can be conveniently separated.
[0197]Periodate cleavage of the olefine (step i) followed by reduction of
the ketone (step ii) can be performed as described in the synthetic
procedures 1a) and 1b). The hydroxyester epimers are separable by
chromatography on silica.
[0198]Fluorination of the alcohol (step iii) with inversion of the
configuration can be carried out with diethylamino sulphur trifluoride or
preferably with bis-(2-methoxyethyl)-aminosulphur trifluoride in
CH.sub.2Cl.sub.2 at -80 to 20.degree. C.
[0199]Saponification of the ester (step iv) can be carried out as
described in the synthetic procedure 1a). Amide formation by reaction of
the acid with R.sup.c--B--NH.sub.2 (step v) can be accomplished as
described in the synthetic procedure 1a) preferably by using
isobutylcarbamoyl chloride as the activating agent.
[0200]Fluorination of the ketone (step vi), saponification (step vii) and
subsequent amide formation with R.sup.c--B--NH.sub.2 (step viii) can be
accomplished as described for step iii)-v).
[0201]Alternatively, the hydroxyester can be converted to the amide with
R.sup.c--B--NH.sub.2 (step ix) with AlMe.sub.3 according to the method of
M. Weinreb et al. (Tetrahedron Lett., 48, 4171, 1977). The relative and
absolute configuration of the amide shown in the scheme was determined by
an X-ray analysis of the amide complexed with factor Xa.
[0202]The alcohol group can be converted to the methylether (step x) using
MeCl, MeBr or preferably MeI in a solvent like THF or MeCN, preferably a
mixture of both and an additive such as AgO at 0-40.degree. C. preferably
at 20.degree. C. Amide formation (xi) can be accomplished according to
step ix) using AlMe.sub.3. Both epimers of the ethers are available as
pure isomers.
d) Modifications of D
##STR00026##
[0204]Amide formation by reaction of the acid with R.sup.c--B--NH.sub.2
can be accomplished as described in the synthetic procedures 1a), the
preferred method involves isobutylcarbamoyl chloride as activating agent
and N-methylmorpholine as base at -20 to 60.degree. C., preferably at
45.degree. C.
[0205]The second amide group can be introduced by reaction of the ester
with D-NH.sub.2 in the presence of AlMe.sub.3 as described in the
synthetic procedure 2c).
e) Modifications of --B--R.sup.c
##STR00027##
[0207]The second amide group can be introduced by reaction of the ester
with R.sup.c--B--NH.sub.2 in the presence of AlMe.sub.3 as described in
the synthetic procedure 2c). Preparation of the anilines
R.sup.c--B--NH.sub.2 are described in C. F. Bigge et al. (patent
application WO 2003045912); R. A. Galemmo et al. (patent application
WO9857937); M. L. Quan et al. (patent application WO 2003047517); I. Zeid
et al. (Journal de la Societe Algerienne de Chimie 4(2), 171, 1994.
[0208]Et in the schemes under procedure 1.a) to e) can be replaced with
another C.sub.1-6 alkyl group, preferably C.sub.1-4 alkyl group. B,
R.sup.c and D in the schemes under procedure 2.a) to e) are as defined
before. D is preferably 4-chlorophenyl. --B--R.sup.c is preferably
2-fluoro-4-(2-oxo-2H-pyridin-1-yl)phenyl.
3. Synthesis of cyclopropane dicarboxamide derivatives via succinimide
##STR00028##
[0209]B, R.sup.c and D are as defined before.
[0210]Preferably D is 4-chlorophenyl. Preferably --B--R.sup.c is
2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenyl. In a suitable solvent such as
e.g. acetonitrile, maleic anhydride 1 is treated with D-NH.sub.2 or
R.sup.c--B--NH.sub.2 to give amido carboxamide-carboxylic acids 2a or 2b,
respectively (steps a/b). They can be converted to the cyclic imides
3a/b, respectively, e.g. by treatment with an acid (e.g. HCl) a Lewis
Acid (e.g. ZnCl.sub.2) or an anhydride (e.g. acetic anhydride) in analogy
to e.g. Pal et al., Synthesis, 10, 2003, 1549; Yoshitake et al., J. Chem.
Soc. Perkin II, 2002, 1611; Dubovchich et al., Bioorg. Med. Chem. Lett.,
12, 2002, 1529; Shin et al., Tet. Lett., 42, 7, 2001, 1325 (steps c/d).
Cyclopropanation of 3a/b to racemic 4a/b, respectively
(R.sup.I.dbd.C.sub.1-6 alkyl), is usually carried out by treatment with
an .alpha.-diazo acetic acid alkyl ester (preferably .alpha.-diazo acetic
acid ethyl ester) in a solvent such as e.g. toluene or xylene at
80-160.degree. C., though conditions analogous to those described e.g. by
Kozhushkov et al., Synthesis, 2003, 956; Kurihara et al., Heterocycles
20, 1983, 1919, or Saegusa et al., J. Org. Chem. 38, 1973, 2319 may also
be used (steps e/f). The racemic cyclopropano-imides 4a/b are then
treated with R.sup.C--BNH.sub.2 or DNH.sub.2, respectively, to give
racemic opened derivative 5 (step g/h). Usually this is carried out in a
suitable solvent such as DMF, whereas usually
R.sup.C--BNH.sub.2/DNH.sub.2 is previously deprotonated with a strong
base such as e.g. NaH. The ester moiety can be derivatized to various
functional groups (leading to racemic 6, step i) using methods generally
known to those skilled in the art. Some typical examples are given below:
[0211]Hydrolysis of racemic 5 (e.g. with aq. LiOH) leads to the
corresponding carboxylic acid (R.sup.II.dbd.COOH) which can be converted
into amides (e.g. R.sup.II.dbd.CONMe.sub.2) by treatment with a suited
amine and a condensating reagent such as e.g. DCC
(dicyclohexylcarbodiimide) or EDCI
(N-3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride).
[0212]Treatment of racemic 5 with an excess of an alkyllithium or
alkylmagnesiumhalide leads to derivatives with R.sup.II.dbd.C(C.sub.1-6
alkyl).sub.2OH. Reduction of racemic 5 (e.g. with NaBH.sub.4 in MeOH)
leads to the derivative with R.sup.II.dbd.CH.sub.2OH that can be oxidized
to the aldehyde (R.sup.II.dbd.CHO) e.g. by a Swern-oxidation. Treatment
of derivatives with R.sup.II.dbd.CH.sub.2OH with a sulfonylating agent
such as e.g. mesylchloride, tosylchloride, triflic anhydride leads to
intermediates with e.g. R.sup.II.dbd.CH.sub.2O Ms, CH.sub.2OTs,
CH.sub.2OTf that can be reacted with a nucleophile "Nu or NuH" such as
e.g. an amine or a heterocycle (e.g. imidazole) to give derivatives with
R.sup.II.dbd.CH.sub.2--Nu. Derivatives obtained by this method for which
R.dbd.CH.sub.2--NHC.sub.1-6 alkyl.sup.1 are readily converted to
derivatives with R.sup.II.dbd.CH.sub.2--NC.sub.1-6
alkyl.sup.1(SO.sub.2C.sub.1-6 alkyl.sup.2),
R.sup.II.dbd.CH.sub.2--NC.sub.1-6 alkyl.sup.1(COC.sub.1-6 alkyl.sup.2),
with R.sup.II.dbd.CH.sub.2--NC.sub.1-6 alkyl.sup.1(COOalkyl.sup.2) by
treatment with a reagent C.sub.1--SO.sub.2C.sub.1-6 alkyl.sup.2, ClCO
C.sub.1-6 alkyl.sup.2, ClCOOC.sub.1-6 alkyl.sup.2, respectively,
preferably in the presence of a base such as e.g. triethylamine.
[0213]Derivatives with R.sup.II.dbd.CHO, COOH, CONHR.sup.III (wherein
R.sup.III.dbd.H or C.sub.1-6 alkyl) may readily be transformed (in one or
more steps) into derivatives with R.sup.II=heterocycle using
methodologies analogous to those described or mentioned e.g. in "Advances
in Heterocyclic chemistry, Monograph series by A. Katritzky (Editor) and
Comprehensive Heterocyclic Chemistry II, a review of Literature
1982-1995, Monograph Series by A. Katritzky (editor); for more specific
examples (e.g. oxazolidines) see e.g.: Cwik et al., Tet. Lett., 43, 2002,
3985; Vorbrueggen et al., Tetrahedron, 49, 1993, 9353.
[0214]Alternatively, the COOR.sup.1-group of racemic 4a/b may be
transformed to the above mentioned groups R.sup.II (step j, leading to
racemic 7a/b) prior to the R.sup.c--BNH.sub.2/DNH.sub.2-promoted imide
opening using the same methods described for step i. The imide opening of
7a/b to racemic 6 is carried out thereafter (steps k/l) in analogy to
steps g/h. If desired or required separation of the enantiomers of the
racemic 4a/b, 5, 6, or 7a/b can be carried out by suitable chiral HPLC.
Steps g-l may, if desired, be carried out on enantiomerically pure 4a/b,
5 or 7a/b as well.
4. Synthesis of Cyclopropane Dicarboxamide Derivatives Via Succinic
Anhydrides
##STR00029##
[0216]R.sup.3 to R.sup.6 in the scheme are hydrogen, C.sub.1-6 alkyl or
C.sub.3-7 cycloalkyl. B, R.sup.c and D are as defined before.
[0217]Preferably D is 4-chlorophenyl. Preferably --B--R.sup.c is
2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenyl. Diacids 1 (Commercially
Available or Known from the Literature) which can exist as mixture of the
racemic cis isomer and the racemic trans isomer are converted to the
racemic cis anhydrides 2 by treatment with neat acetic anhydride at
reflux temperature or with trifluoroacetic anhydride at 0.degree. (scheme
1, step a). The trans diacids cannot react to the corresponding
anhydrides. The racemic cis anhydrides 2 are separated off by
destillation. Alternatively, the reaction mixture is concentrated and the
crude product is used for the next step without further purification.
Racemic anhydrides 2 are reacted with anilines D-NH.sub.2 in an inert
solvent such as THF to give racemic cyclopropane monocarboxamides 3 (step
b). The products resulting from attack at the less hindered carbon are
formed predominantly. Esterification of monocarboxamides 3 (step c) is
usually accomplished by dissolving them in an alcohol such as MeOH and
EtOH followed by treatment with thionyl chloride at 0.degree. C. in
analogy to J. Ind. Chem. Soc. 1992, 69(10), 683-4. Racemic esters 4 are
then reacted with anilines R.sup.c--B--NH.sub.2 (step d). Anilines are
preactivated with AlMe.sub.3 in a solvent such as toluene or dioxane and
then treated with an ester 4 at elevated temperature (usually 90.degree.
C.) to give racemic 1,2-cyclopropandicarboxamides 5.
5. Synthesis of Cyclopropane Dicarboxamide Derivatives Via Intramolecular
Cyclopropanation
##STR00030##
[0219]B, R.sup.c and D are as defined before.
[0220]An Allylester derivative 1, wherein R.sup.1.dbd.COC.sub.1-6 alkyl,
COOC.sub.1-6 alkyl or COOallyl and R.sup.II.dbd.H, C.sub.1-6 alkyl or a
suitably O-protected hydroxymethyl, is converted to the diazo derivative
2 using a diazo transfer reagent such as e.g. tosylazide,
diphenylphosphorylazide or 4-acetamidobenzensulfonyl azide in the
presence of a base such as e.g. N,N-ethyldiisopropylamine (step a).
Optionally, for derivatives with R.sup.I.dbd.COC.sub.1-6 alkyl a
deacylation to R.sup.I.dbd.H may be carried out by treatment with e.g.
LiOH (step b). Intramolecular cyclopropanation e.g. using a chiral or a
achiral catalyst derived e.g. from rhodium, copper, cobalt or ruthenium
(as described e.g. in J. Med. Chem. 2004,47, p 456-66, Chem. Commun.
1997, p 211-2, Org. Lett. 2002, p 1911-4, Tet. Lett, 2001, p 2521-4, Ang.
Chem. Int. Ed. 1999, p 700-2.) leads to the racemic or enantiomerically
enriched (up to >98% ee) bicyclic lactone derivative 3 (step c).
Alternatively, for R.sup.I.dbd.COC.sub.1-6 alkyl, COO C.sub.1-6 alkyl,
COOallyl, Allylester 1 can be directly transformed into lactone 3, e.g.
by treatment with 12 in presence of K.sub.2CO.sub.3 as described e.g. by
Toeke et al. in Tetrahedron 1993, 49, p 5133-46, or by treatment with a
chloro-, bromo, iodo-, methanesulfonyloxy- or
trifluormethanesulfonyloxy-methyloxirane after deprotonation of 1 with a
strong base such as e.g. NaH as described e.g. by Burgess et al. in J.
Org. Chem. 1992, 57, p 5931-6. The lactone 3 can be converted to the
anhydride 4 by treatment with an oxidizing agent such as e.g. Jones
reagent, pyridinium dichromate, pyridinium chlorochromate and subsequent
treatment with a dehydrating agent such as e.g. thionylchloride or
oxalylchloride (step d). Treatment of the anhydride 4 with either
H.sub.2N--B--R.sup.c or H.sub.2N-D in the presence of a base such as e.g.
pyridine leads to the amido carboxylic acids 5 (step e) and 6 (step f),
respectively, or mixtures of the two (attack of the amine usually
occurring preferentially at the sterically less hindered carbonyl group).
Both 5 and 6 can be converted to the methyl esters 7 and 8 by treatment
with thionylchloride in MeOH or with iodomethane in presence of potassium
carbonate (steps g and h) or to the imides 9 and 10 (steps i and j),
respectively, by treatment with a dehydrating agent such as e.g.
thionylchloride. Amido carboxylic acids 11 and 12 can be obtained by
opening of the lactone 3 with either H.sub.2N--B--R.sup.c or H.sub.2N-D
(previously treated with a strong base such as e.g. lithium
bis(trimethylsilyl)amide) and subsequent oxidation of the resulting
alcohol using a oxidative agent such as e.g. Jones reagent (steps k and
1). In analogy to steps g or h they can be converted to the corresponding
methylesters 13 or 14 (steps m and n) or to the imides 9 or 10 (steps o
and p).
[0221]Esters 7 and 13 are reacted with H.sub.2N--B--R.sup.c or H.sub.2N-D,
respectively (preactivated with AlMe.sub.3) to bisamide 15 (steps q and
r). Similarly esters 8 and 14 are reacted to bisamide 16 (steps and t).
Bisamide 15 may alternatively be obtained by reaction of imide 9 with
H.sub.2N--B--R.sup.c previously pretreated with a strong base such as
e.g. lithium bis(trimethylsilyl)amide (step u), bisamide 16 by reaction
of imide 10 with H.sub.2N-D (pretreated with a strong base such as e.g.
lithium bis(trimethylsilyl)amide (step v). These reactions are usually
carried out in an inert solvent such as THF, dioxane or toluene at
temperatures ranging from RT to 150.degree. C.
[0222]If desired R.sup.I may be derivatized to other functional groups.
Typical transformations are e.g.: Hydrolysis of R.sup.1.dbd.COOC.sub.1-6
Alkyl to R.sup.1.dbd.COOH with e.g. LiOH, reduction of
R.sup.1.dbd.COOC.sub.1-6 Alkyl to R.sup.1.dbd.CH.sub.2OH with e.g.
NaBH.sub.4. Derivatives with R.sup.1.dbd.COOH can be converted into
amides (e.g. R.sup.1.dbd.CONMe.sub.2) by treatment with a suited amine
and a condensating reagent such as e.g. DCC (dicyclohexylcarbodiimide) or
EDCI (N-3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride).
Treatment of derivatives with R.dbd.CH.sub.2OH with a sulfonylating agent
such as e.g. mesylchloride, tosylchloride, triflic anhydride leads to
intermediates with e.g. R.sup.II.dbd.CH.sub.2O Ms, CH.sub.2OTs,
CH.sub.2OTf that can be reacted with a nucleophile "Nu or NuH" such as
e.g. an amine, a heterocycle, or a source of a cyanide or a fluoride
anion, or a heterocycle, to give derivatives with
R.sup.I.dbd.CH.sub.2--Nu. R.sup.I or R.sup.II.dbd.CH.sub.2OH can be
oxidized to R.sup.I or R.sup.II.dbd.CHO e.g. by a Swern-oxidation and
derivatized to R.sup.I or R.sup.II.dbd.C.sub.1-6 alkyl by Wittig-type
reaction and subsequent hydrogenation of the double bond.
[0223]For derivatives with R.sup.II=suitably protected hydroxymethyl,
deprotection may be carried out to R.sup.II.dbd.CH.sub.2OH using standard
procedures commonly known to those in the art (e.g. desilylation with
TBAF, or de-paramethoxybenzylation with DDQ) and e.g. oxidized to
R.sup.II.dbd.COOH or formyl. R.sup.II.dbd.CH.sub.2OH, COOH or formyl can
be further derivatized using the same methodologies described above for
R.sup.I.dbd.CH.sub.2OH or COOH.
[0224]As described above, the compounds of formula (I) are active
compounds and inhibit the coagulation factor Xa. These compounds
consequently influence both platelet activation which is induced by this
factors and plasmatic blood coagulation. They therefore inhibit the
formation of thrombi and can be used for the treatment and/or prevention
of thrombotic disorders, such as, amongst others, arterial and venous
thrombosis, deep vein thrombosis, peripheral arterial occlusive disease
(PAOD), unstable angina pectoris, myocardial infarction, coronary artery
disease, pulmonary embolism, stroke (cerebral thrombosis) due to atrial
fibrillation, inflammation and arteriosclerosis. The compounds of the
present invention can also be used in the treatment of acute vessel
closure associated with thrombolytic therapy and restenosis, e.g. after
transluminal coronary angioplasty (PTCA) or bypass grafting of the
coronary or peripheral arteries and in the maintenance of vascular access
patency in long term hemodialysis patients. F.Xa inhibitors of this
invention may form part of a combination therapy with an anticoagulant
with a different mode of action or with a platelet aggregation inhibitor
or with a thrombolytic agent. Furthermore, these compounds have an effect
on tumor cells and prevent metastases. They can therefore also be used as
antitumor agents.
[0225]Prevention and/or treatment of thrombotic disorders, particularly
arterial or deep vein thrombosis, is the preferred indication.
[0226]The invention therefore also relates to pharmaceutical compositions
comprising a compound as defined above and a pharmaceutically acceptable
excipient.
[0227]The invention likewise embraces compounds as described above for use
as therapeutically active substances, especially as therapeutically
active substances for the treatment and/or prophylaxis of diseases which
are associated with the coagulation factor Xa, particularly as
therapeutically active substances for the treatment and/or prophylaxis of
thrombotic disorders, arterial thrombosis, venous thrombosis, deep vein
thrombosis, peripheral arterial occlusive disease, unstable angina
pectoris, myocardial infarction, coronary artery disease, pulmonary
embolism, stroke due to atrial fibrillation, inflammation,
arteriosclerosis, acute vessel closure associated with thrombolytic
therapy or restenosis, and/or tumor
[0228]In another preferred embodiment, the invention relates to a method
for the therapeutic and/or prophylactic treatment of diseases which are
associated with the coagulation factor Xa, particularly for the
therapeutic and/or prophylactic treatment of thrombotic disorders,
arterial thrombosis, venous thrombosis, deep vein thrombosis, peripheral
arterial occlusive disease, unstable angina pectoris, myocardial
infarction, coronary artery disease, pulmonary embolism, stroke due to
atrial fibrillation, inflammation, arteriosclerosis, acute vessel closure
associated with thrombolytic therapy or restenosis, and/or tumor, which
method comprises administering a compound as defined above to a human
being or animal subject suffering from a disease associated with the
coagulation factor Xa.
[0229]The inhibition of the coagulation factor Xa by the compounds of the
present invention can be demonstrated with the aid of a chromogenic
peptide substrate assay such as described in the Examples hereinafter.
[0230]The activity of the low molecular weight substances can, moreover,
be characterized in the "prothrombin time" (PT) clotting test. The
substances are prepared as a 10 mM solution in DMSO and thereafter made
up to the desired dilution in the same solvent. Thereafter, 0.25 ml of
human plasma (obtained from whole blood anticoagulated with 1/10 volume
of 108 mM Na citrate) was placed in the instrument-specific sample
container. In each case 5 .mu.l of each dilution of the
substance-dilution series was then mixed with the plasma provided. This
plasma/inhibitor mixture was incubated at 37.degree. C. for 2 minutes.
Thereafter, there were pipetted to the semi-automatic device (ACL,
Automated Coagulation Laboratory (Instrument Laboratory)) 50 .mu.l of
plasma/inhibitor mixture in the measurement container. The clotting
reaction was initiated by the addition of 0.1 ml of Dade.RTM.
Innovin.RTM. (recombinant human tissue factor combined with calcium
buffer and synthetic phospholipids, Dade Behring, Inc., Cat. B4212-50).
The time up to the fibrin cross-linking was determined p
hotooptically
from the ACL. The inhibitor concentration, which brought about a doubling
of the PT clotting time, was determined by fitting the data to an
exponential regression (XLfit).
[0231]The compounds of the present invention can furthermore be
characterised by the Activated Partial Thromboplastin time (aPTT). This
coagulation test can e.g. be run on the ACL 300 Coagulation System
(Instrumentation Laboratory) automatic analyzer. The substances are
prepared as a 10 mM solution in DMSO and thereafter made up to the
desired dilution in the same solvent. The test is performed with the
Dade.RTM. Actin.RTM. FS Activated PTT reagent (purified soy phosphatides
in 1.0.times.10.sup.-4M ellagic acid, stabilizers and preservative, Dade

plasma (obtained from whole blood anticoagulated with 1/10 volume of 108
mM Na citrate) are spiked with 5 .mu.l of test compound in at least 6
concentrations. 501l plasma at 4.degree. C. containing 1/50 vol.
inhibitor in solvent are incubated with 50 .mu.l Dade.RTM. Actin.RTM. FS
Activated PTT reagent in water at 37.degree. C. for 3 min., then 50 .mu.l
CaCl2.2H2O 25 mM in water at 37.degree. C. are added. The time up to the
fibrin cross-linking was determined p
hotooptically from the ACL. The
inhibitor concentration, which brought about a doubling of the APTT
clotting time, was determined by fitting the data to an exponential
regression (XLfit).
[0232]The Ki values of the active compounds of the present invention
preferably amount to about 0.001 to 50 .mu.M, especially about 0.001 to 1
.mu.M. The PT values preferably amount to about 0.5 to 100 .mu.M,
especially to about 0.5 to 10 .mu.M. The aPTT values preferably amount to
about 0.5 to 100 .mu.M, especially to about 0.5 to 10 .mu.M.
[0233]The compounds of formula I and/or their pharmaceutically acceptable
salts can be used as medicaments, e.g. in the form of pharmaceutical
preparations for enteral, parenteral or topical administration. They can
be administered, for example, perorally, e.g. in the form of tablets,
coated tablets, dragees, hard and soft gelatine capsules, solutions,
emulsions or suspensions, rectally, e.g. in the form of suppositories,
parenterally, e.g. in the form of injection solutions or suspensions or
infusion solutions, or topically, e.g. in the form of ointments, creams
or oils. Oral administration is preferred.
[0234]The production of the pharmaceutical preparations can be effected in
a manner which will be familiar to any person skilled in the art by
bringing the described compounds of formula I and/or their
pharmaceutically acceptable salts, optionally in combination with other
therapeutically valuable substances, into a galenical administration form
together with suitable, non-toxic, inert, therapeutically compatible
solid or liquid carrier materials and, if desired, usual pharmaceutical
adjuvants.
[0235]Suitable carrier materials are not only inorganic carrier materials,
but also organic carrier materials. Thus, for example, lactose, corn
starch or derivatives thereof, talc, stearic acid or its salts can be
used as carrier materials for tablets, coated tablets, dragees and hard
gelatine capsules. Suitable carrier materials for soft gelatine capsules
are, for example, vegetable oils, waxes, fats and semi-solid and liquid
polyols (depending on the nature of the active ingredient no carriers
might, however, be required in the case of soft gelatine capsules).
Suitable carrier materials for the production of solutions and syrups
are, for example, water, polyols, sucrose, invert sugar and the like.
Suitable carrier materials for injection solutions are, for example,
water, alcohols, polyols, glycerol and vegetable oils. Suitable carrier
materials for suppositories are, for example, natural or hardened oils,
waxes, fats and semi-liquid or liquid polyols. Suitable carrier materials
for topical preparations are glycerides, semi-synthetic and synthetic
glycerides, hydrogenated oils, liquid waxes, liquid paraffins, liquid
fatty alcohols, sterols, polyethylene glycols and cellulose derivatives.
[0236]Usual stabilizers, preservatives, wetting and emulsifying agents,
consistency-improving agents, flavour-improving agents, salts for varying
the osmotic pressure, buffer substances, solubilizers, colorants and
masking agents and antioxidants come into consideration as pharmaceutical
adjuvants.
[0237]The dosage of the compounds of formula I can vary within wide limits
depending on the disease to be controlled, the age and the individual
condition of the patient and the mode of administration, and will, of
course, be fitted to the individual requirements in each particular case.
For adult patients a daily dosage of about 1 to 1000 mg, especially about
1 to 300 mg, comes into consideration. Depending on severity of the
disease and the precise pharmacokinetic profile the compound could be
administered with one or several daily dosage units, e.g. in 1 to 3
dosage units.
[0238]The pharmaceutical preparations conveniently contain about 1-500 mg,
preferably 1-100 mg, of a compound of formula I.
[0239]The following Examples serve to illustrate the present invention in
more detail. They are, however, not intended to limit its scope in any
manner.

[0499]Step 1:
[0500]As solution of 10 g (100 mmol) of 1,3-dioxep-5-ene in 50 ml of
dichloromethane was treated with 300 mg (0.68 mmol) of dirhodium
tetraacetate and heated to reflux. A solution of 23.9 g of
ethyldiazoacetate in 35 ml of dichloromethane was added dropwise over a
period of 3-4 hrs and the resulting mixture was stirred at reflux during
10 hrs. After cooling to RT the mixture was filtered through silica gel
and concentrated. The resulting yellow oil was dissolved in a 0.5 M HCl
solution in EtOH and refluxed during 3 hrs. Evaporation of the solvent

methyl-cyclopropanecarboxylic acid ethyl ester in 10 ml of acetone was
treated at 0.degree. C. with 390 ml of Jones reagent and stirred at RT
for 2 hrs. The mixture was treated with 100 mg of NaHSO.sub.3, stirred
for 15 min and filtered. Evaporation of the solvend gave a greenish solid
that was dissolved in dichloromethane, treated with 76 ul of
thionylchloride and stirred at RT during 2 hrs. Evaporation of the
solvent and chromatography on silica gel with AcOEt gave 136 mg (35%) of
(1RS, 5SR, 6RS)

Step 5:
[0504]A solution of 27.5 mg (0.21 mmol) of 2-amino-5-chloropyridine in 1
ml of THF was cooled to -78.degree. C. and treated with 0.26 ml of a 1M
lithium bis(trimethylsilyl)amide-solution in THF and stirred for 30 min.

6RS).sub.2-[2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenylcarbamoyl]-3-hydroxy-
methyl-cyclopropanecarboxylic acid ethyl ester dissolved in 0.5 ml of THF
were added portionwise. The mixture was allowed to reach RT, stirred for
10 hrs and treated with 1 ml of methanol. Evaporation of the solvent and

Example F
[0698]Factor Xa activity was measured spectrop
hotometrically in microtiter
plates in a final volume of 150 .mu.l using the following conditions:
Inhibition of human factor Xa (Enzyme Research Laboratories) was tested
at an enzyme concentration of 3 nM using the chromogenic substrate S-2222
(Chromogenix AB, Molndal, Sweden) at 200 nM. The reaction kinetics of the
enzyme and the substrate were linear with both time and the enzyme
concentration. The inhibitors were dissolved in DMSO and tested at
various concentrations up to 100 .mu.M. The inhibitors were diluted using
HNPT buffer consisting of HEPES 100 mM, NaCl 140 mM, PEG 6000 0.1% and
Tween 80 0.02%, pH 7.8. The cleavage of S-2222 by human factor Xa was
followed at 405 nm for 5 minutes at room temperature. The velocity of the
reaction was determined by the autoreader from the slope of the linear
regression fit to 7 time points (1 minute). The initial velocity for each
inhibitor concentration was determined by the slope of at least 4 time
points in the linear phase by a linear regression fit (mOD/min.sup.2).
Apparent dissociation constants K.sub.i were calculated according to
Cheng and Prusoff [Cheng, Y. C.; Prusoff, W. H. Relationship between the
inhibition constant (K.sub.i) and the concentration of the inhibitor that
causes 50 percent inhibition (IC.sub.50) of an enzyme reaction. Biochem.
Pharmacol. 1973, 22, 3099-3108.] based on the IC.sub.50 and the
respective K.sub.m, determined previously
(K.sub.i=IC.sub.50/(1+S/K.sub.m)). The K.sub.m for the substrate used was
determined under the conditions of the test with at least 5 substrate
concentrations ranging from 0.5 to 15 times K.sub.m. [Lottenberg R, Hall

peptide p-nitroanilide substrates. Substrate selectivity and examination
of hydrolysis under different reaction conditions. Biochim Biophys Acta.

inhibition of cholinesterase by physostigmine and prostigmine. J. Biol.
Chem. 1942, 146, 85-93.]. The K.sub.m for S-2222 amounted to 613 .mu.M.
