実験手順

N-[(9H-fluoren-9-yloxy)carbonyl]-3-(t-butoxycarbonyl)-L-alanine and 3-(p-t-butoxyphenyl)-L-alanine t-butyl ester were coupled to give N-[N-[(9H-fluoren-9-yloxy)carbonyl] -3-(t-butoxycarbonyl)-L-alanyl]-3-(p-t-butoxyphenyl)-L-alanine t-butyl ester and 5 ml of piperidine and the reaction solution was evaporated. The residue was suspended in methanol and insoluble material was filtered off. The filtrate was evaporated and chromatographed on silica gel using ethyl acetate to yield 2 g of 3-(t-butoxyphenyl)-N-[3-(p-t-butoxy-carbonyl)-L-alanyl]-L-alanine t-butyl ester.
