実験手順

Nα-t-Butoxycarbonyl-L-tryptophyl-O-benzyl-L-seryl-O-benzyl-D-tyrosyl-D-alanine resin is obtained according to the procedure of Example 1 by treating 20 g. of Nα-t-butoxycarbonyl-D-alanine resin, 0.0132 mol, with 7.4 g., 0.02 mol, of Nα-t-butoxycarbonyl-O-benzyl-D-tyrosine and 4.1 g., 0.02 mol, of dicyclohexylcarbodiimide, (2) 6.0 g., 0.02 mol, of Nα-t-butoxycarbonyl-O-benzyl-L-serine and 4.1 g. of dicyclohexylcarbodiimide, and (3) 6.1 g. of Nα-t-butoxycarbonyl-L-tryptophan and 4.1 g. of dicyclohexylcarbodiimide.
