Procedure
The preparation was carried out in the same manner as in Example 1, except that 3.02 mg of (2S,4S)-N-phenyloxycarbonyl-4-diphenylphosphino-2-diphenylphosphinomethylpyrrolidine (PPPM) was used instead of 3.02 mg of PCPPM of Example 1. After the reaction, the residual ratio of 2-benzylidene-3-(cis-hexahydro-2-isoindolinylcarbonyl)propionic acid was 9.74%, and the optical purity of mitiglinide thus obtained was 94.5% e.e.
