Reaction Steps
Condensation of BocDPheOH (2.65 g.) and HLeu-MetNH2 hydrochloride salt (Example 1, 2.98 g.) by the mixed anhydride method using isobutyl chloroformate gave BocDPhe-Leu-MetNH2 in 57% yield. De-t-butoxycarbonylation of BocDPhe-Leu-MetNH2 (2.7 g.) using hydrogen chloride in ethyl acetate gave HDPhe-Leu-MetNH2 hydrochloride salt in 82% yield.
