実験手順

To a solution of the compound (1.90 g), which had been obtained in (1), in anhydrous dichloromethane (20 ml), trifluoroacetic acid (10 ml) was added dropwise under ice cooling, followed by stirring at the same temperature for 10 minutes and then at room temperature for 10 minutes. The reaction mixture was diluted with 1,2-dichloroethane and concentrated by evaporation under reduced pressure. The residue was washed successively with hexane and diethyl ether by decantation and the solvent was distilled off, whereby a crude 3-[4-[2,3-di(4-nitrobenzyloxycarbonyl)guanidino]-butanoylamino]azetidine trifluoroacetate (1.93 g) was obtained. The product was provided for use in the subsequent reaction without isolation.
