实验过程

Condensation of BocProOH (4.30 g.) and HMePheOMe (2.74 g.) by the mixed anhydride method using diphenylphosphinyl chloride gave BocPro-MePheOMe in 77% yield. Demethylation of BocPro-MePheOMe (3.0 g.) using aqueous sodium hydroxide gave BocPro-MePheOH in 83% yield. Condensation of BocPro-MePheOH (1.71 g.) and HPheOBz (2.14 g.) using dicyclohexylcarbodiimide and N-hydroxysuccinimide gave BocPro-MePhe-PheOBz in 76% yield. Debenzylation of BocPro-MePhe-PheOBz (2.0 g.) by hydrogenation with palladium catalyst gave BocPro-MePhe-PheOH in 100% yield.
