Reaction Steps

Condensation of BocLeuOH (3.49 g.) and HDMetNH2 (2.0 g.) by the mixed anhydride method using isobutyl chloroformate gave BocLeu-DMetNH2 in 70% yield. De-t-butoxycarbonylation of BocLeu-DMetNH2 (2.74 g.) using hydrogen chloride in ethyl acetate gave HLeu-DMetNH2 in 91% yield. Condensation of BocGlyOSu (2.66 g.) and HLeu-DMetNH2 (1.95 g.) by the active ester method gave BocGly-Leu-DMetNH2 in 92% yield. De-t-butoxycarbonylation of BocGly-Leu-DMetNH2 (2.30 g.) using hydrogen chloride in acetic acid gave HGly-Leu-DMetNH2 in 79% yield.
