Title (EN) PROCESS FOR THE PREPARATION OF (3S,4S)-TETRAHYDROFURAN-3-YL 4-ISOPROPYL-6,7-DIHYDRO-3H-IMIDAZO[4,5-C]PYRIDINE-5(4H)-CARBOXYLATE
(FR) PROCÉDÉ DE PRÉPARATION DE (3S,4S)-TÉTRAHYDROFURAN-3-YL 4-ISOPROPYL -6,7-DIHYDRO -3 H-IMIDAZO [4,5-C] PYRIDINE -5 (4H)-CARBOXYLATE
Abstract:
(EN) The invention relates to an improved process for the synthesis of (3S,4S)-tetrahydrofuran-3-yl 4-isopropyl-6,7-dihydro-3H-imidazo[4,5-c]pyridine-5(4H)-carboxylate, and pharmaceutically acceptable salts thereof, such as the methanesulphonic acid salt.
(FR) L'invention concerne un procédé amélioré de synthèse de (3S,4S)-tétrahydrofuran-3-yl 4-isopropyl -6,7-dihydro -3 H-imidazo [4,5-c] pyridine -5 (4H)-carboxylate, et des sels pharmaceutiquement acceptables de celui-ci, tels que le sel d'acide méthanesulfonique.
