Condesation of BocProOH (6.46 g.) and N-hydroxysuccinimide (3.5 g.) using dicyclohexylcarbodiimide gave BocProOSu in 75% yield. Condensation of BocProOSu (5.0 g.) and HDPheOH (2.75 g.) by the salt coupling method gave BocPro-DPheOH in 67% yield. Condensation of BocPro-DPheOH (3.98 g.) and HPheOMe hydrochloride salt (2.4 g.) using dicyclohexylcarbodiimide and N-hydroxysuccinimide gave BocPro-DPhe-PheOMe in 74% yield. Hydrazinolysis of Boc-Pro-DPhe-PheOMe (3.14 g.) gave BocPro-DPhe-PheNHNH2 in 79% yield.
