実験手順

Coupling of N-(3,5-dimethylbenzoyl)-N-methyl-O-benzyl-(D)-tyrosine (prepared by O-benzylation of N-(3,5-dimethylbenzoyl)-N-methyl-(D)-tyrosine (example 64)) with (L)-tryptophan methyl ester hydrochloride according to example 1 followed by hydrolysis of the methyl ester moiety according to example 12 gives N-(3,5-dimethylbenzoyl)-N-methyl-O-benzyl-(D)-tyrosyl-(L)-tryptophan; FAB-MS m/e 602 (M-H)-.
