実験手順
Boc-Phe-Gly-OBzl (6.2 g, 15 mmole) was suspended in the mixtured solvent of MeOH (80 ml) and AcOH (30 ml), and then H2 gas was passed through the solution in the presence of Pd-C for 4 hours. Pd-C was removed by filtration, and the solvent was distilled off. The thus-obtained residue was recrystalized two times with AcOEt/n-hexane to obtain the object product (4.49 g, 92.8%).
