实验过程

Condensation of BocPro-DPhe-PheNHNH2 (Example 23, 0.717 g.) and HDPhe-Leu-NleNH2 hydrochloride salt (0.585 g.) by the acyl azide method (Yajima et al., Chem. Pharm. Bull., vol. 19, p. 1900, 1971) gave BocPro-DPhe-Phe-DPhe-Leu-NleNH2 in 51% yield. De-t-butoxycarbonylation of BocPro-Dphe-Dphe-Leu-NleNH2 (0.500 g.) using hydrogen chloride in acetic acid gave HPro-DPhe-Phe-DPhe-Leu-NleNH2, which was isolated as the amorphous white solid hydrochloride salt trihydrate in 36% yield.
