PROCEDURE

实验过程

Condensation of BocPro-DTrp-MePheOH (0.800 g.) and HDTrp-Leu-MetNH2 acetate salt (part B of Example 17, 0.721 g.) using dicyclohexylcarbodiimide and 1-hydroxybenzotriazole gave BocPro-DTrp-MePhe-DTrp-Leu-MetNH2 in 31% yield. De-t-butoxycarbonylation of BocPro-DTrp-MePhe-DTrp-Leu-MetNH2 (0.400 g.) using trifluoroacetic acid in dimethyl sulfide and ethanedithiol gave HPro-DTrp-MePhe-DTrp-Leu-MetNH2, which was isolated as the amorphous white solid phosphate (1:2) salt dihydrate in 23% yield.
