実験手順

Allyl 3-aminobenzyloxyacetate was condensed with (2S,4S)-4-acetylthio-1-allyloxycarbonyl-2-carboxypyrrolidine by the method described in example 3 for allyl 3-aminophenoxyacetate, except that crude product was purified by chromatography on silica, using a gradient from di-chloromethane to dichloromethane/diethyl ether (85:15), to give (2S,4S)-4-acetylthio-1-allyloxycarbonyl-2-(3(allyloxycarbonylmethoxymethyl)phenylcarbamoyl)pyrrolidine.
