<p>A novel production process which comprises reacting a benzylsuccinic acid derivatives represented by formula (I), with a benzy halide such as benzyl bromide to give a benzyl ester derivative represented by formula (III), then purifying and debenzylating the same optionally followed by the conversion into desired salts thereof to thereby efficiently and stably supply highly pure benzylsuccinic acid derivatives useful as a remedy for diabetes.</p> |
