  • Process for producing enantiomer of amlodipine in high optical purity
    Patent number: 8445688
    Abstract: The present invention relates to a process for preparation of optically pure (S)-amlodipine-L-hemitartrate DMF solvate comprising the steps of treating (R,S) amlodipine base with L-tartaric acid in the presence of dimethyl formamide and a co-solvent. The invention also relates to a process for converting (R) or (S)-amlopidine-L-hemitartrate DMF solvate into their besylates without isolating free chiral amlopidine base after solution.
