Objective: To optimize the current synthesis routes for developing a new synthetic route for mitiglinide calcium production. Methods:(S)-2-benzylsuccinic acid and CDI were used as the starting materials to get the active amide. Then the active amide was reacted with the hydrochloride salt of cis-hexahydroisoindoline and benzyl chloride to get purified benzyl ester; thereafter,debenzylation and calcification were done to get mitiglinide calcium. Results: Mitiglinide calcium was synthesized with a total yield...
