The present invention relates to a novel and improved process for preparing (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4'-(trifluo-romethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid of the formula (I) and to novel crystalline forms of it, which is i.a. the pseudopolymorphic form monohydrate I (I-M-I) or the pseudopolymorphic form monohydrate II (I-M-II), furthermore the present invention relates to a novel and selective crystallization process for preparation of the pseudopolymorphic form monohydrate I (I-M-I) or the pseudopolymorphic form monohydrate II (I-M-II), preferably monohydrate I of formula (I-M-I) and to pharmaceutical compositions comprising monohydrate I of formula (I-M-I) and to its use for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of pulmonary and cardiopulmonary and cardiovascular diseases.

Process for preparing (5S)-{[2-(4-carboxyphenyl)ethyl] |2-(2-{|3-chloro-4'-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]aminol-5,6,7,8-tetrahydroquinoline-2-carboxylic acid and its crystalline forms for use as pharmaceutically active compound

The present invention relates to the use of (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4'-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid of formula (I), prefer-ably in form of one of its salts or solvates or hydrates, preferably (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4′-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid in form of monohydrate (I) of formula (I-M-I) or (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4′-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)-ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid inform of mono hydrate (II) of formula (I-M-II), in the inhalative treatment of cardiopulmonary and pulmonary disorders, such as pulmonary arterial hypertension (P AH), chronic tromboembolic pulmonary hypertension (CTEPH) and pulmonary hypertension (PH) associated with chronic lung disease (PH group 3) such as pulmonary hypertension in chronic obstructive pulmonary disease (PH-COPD) and pulmonary hypertension with idiopathic interstitial pneumonia (PH-IIP), characterized in that an inhalative dosage form comprising 240 to 4000 μg, preferably 480 to 2000 μg of (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4′-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxy lie acid of formula (I), preferably in form of one of its salts or solvates or hydrates, preferably in form of monohydrate I of formula (I-M-I) or (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4′-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxy lie acid in form of mono hydrate (II) of formula (I-M-II), is administered to a patient in need thereof once or twice daily for a period of at least two consecutive days, preferably at least 2 to 7 consecutive days, preferably for a period of at least 14 consecutive days, in particular from after onset of treatment for the whole course of the disease, wherein the inhalative dosage form preferably comprises the combination of the active ingredient and a pharmaceutically suitable excipient or carrier, while preferably the active ingredient and a pharmaceutically suitable excipient are filled in a hard capsule.

Treatment of cardiopulmonary disorders

The present invention relates to a process for preparing 4-{[(2S)-2-{4-[5-chloro-2-(4-chloro-1H-1,2,3-triazol-1-yl)phenyl]-5-methoxy-2-oxopyridin-1(2H)-yl}butanoyl]amino}-2-fluorobenzamide (I) or 4-({(2S)-2-[4-{5-chloro-2-[4-(trifluoromethyl)-1H-1,2,3-triazol-1-yl]phenyl}-5-methoxy-2-oxopyridin-1(2H)-yl]butanoyl}amino)-2-fluorobenzamide (II) from 2,5-dimethoxypyridine (III), 1-(2-bromo-4-chlorophenyl)-4-chloro-1H-1,2,3-triazole (X-Cl) or 1-(2-bromo-4-chlorophenyl)-4-(trifluoromethyl)-1H-1,2,3-triazole (X-CF), 4-amino-2-fluorbenzamide (XIII) and (2R)-2-aminobutanoic acid (XVII).

Preparative process

What is described herein relates to a method of selectively hydrolyzing an enantiomer of an alpha haloalkanoic acid according to formula I employing a polypeptide having dehalogenase activity comprising an amino acid sequence as set forth in SEQ ID NO. 1 or SEQ ID NO. 4 or a sequence with at least 80% sequence identity to either of said sequences and to the use of said method.
