PROCESS FOR CRYSTALLIZATION OF RAMIPRIL AND PREPARATION OF A HYDRATED FORM THEREOF
The present invention relates to a novel method for obtaining (2S,3aS,6aS)-1-[(S)-2-[[(S)-1-(ethoxycarbonyl)-3-phenylpropyl]-amino] propanoyl] octahydro cyclopenta[b] pyrrole-2-carboxylic acid, viz. Ramipril(I) in high optical purity, free of other stereoisomers, and in high bulk density. The presen...

| Zusammenfassung: | The present invention relates to a novel method for obtaining (2S,3aS,6aS)-1-[(S)-2-[[(S)-1-(ethoxycarbonyl)-3-phenylpropyl]-amino] propanoyl] octahydro cyclopenta[b] pyrrole-2-carboxylic acid, viz. Ramipril(I) in high optical purity, free of other stereoisomers, and in high bulk density. The present invention also relates to a novel hydrated form of Ramipril(I) and a process for preparation thereof.
L'invention concerne un procédé d'élaboration d'acide (2S,3aS,6aS)-1-[(S)-2-[[(S)-1-(éthoxycarbonyle)-3-phénylpropyle]-amino] propanoyle] octahydro cyclopenta[b] pyrrole-2-carboxylique, à savoir Ramipril(I), de pureté optique élevée, sans autres stéréoisomères, et de poids volumétrique élevé. L'invention concerne également une forme hydratée de Ramipril(I) et un procédé d'élaboration correspondant. |
