実験手順

To a solution of (2S,4S)-2-aminomethyl-1-(4-nitrobenzyloxycarbonyl)-4-(triphenylmethylthio)pyrrolidine (7.78 g) in a mixture of tetrahydrofuran (120 ml) and water (40 ml) was added dropwise chloroacetyl chloride (1.23 ml) with stirring under ice-cooling, keeping the pH 8-10 with triethylamine. The mixture was stirred at the same temperature for 1 hour. The reaction mixture was evaporated in vacuo to remove the organic layer. The resulting residue was extracted twice with ethyl acetate (100 ml). The extract was washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate and evaporated in vacuo to give (2S,4S)-2-(chloroacetylamino)methyl-1-(4-nitrobenzyloxy-carbonyl)-4-(triphenylmethylthio)pyrrolidine (7.35 g).
