Rapid resolution process for clopidogrel base and a process for preparation of clopidogrel bisulfate polymorph - form i |
abstract |
The present invention discloses a rapid resolution process of racemic clopidogrel base followed by conversion of the resolved (S) isomer to crystalline Clopidogrel bisulfate Form I. The invention also discloses novel racemization process of the unwanted (R) isomer of clopidogrel base. The invention further discloses an improved process for preparation of acid addition salts of clopidogrel. |
