Reaction Steps
Following the procedure described in example 12 and starting from N-(3,5-dimethylbenzoyl)-N-cyclohexyl-(D)-phenylalanine (prepared by reductive alkylation of (D)-phenylalanine methyl ester with cyclohexanone in the presence of sodium cyanoborohydride followed by N-acylation with 3,5-dimethylbenzoyl chloride in the presence of DMAP and hydrolysis of the methyl ester moiety according to example 1 and (L)-tryptophan methyl ester hydrochloride gives N-(3,5-dimethylbenzoyl)-N-cyclohexyl-(D)-phenylalanyl-(L)-tryptophan; FAB-MS m/e 566 (M+H)+.
