実験手順

Coupling of N-(3,5-dimethylbenzoyl)-N-methyl-(D)-phenylalanine (derived from the corresponding methylester described in example 78 by hydrolysis with lithium hydroxide in methanol/water: [a]D =+88° (c=1.0, ethanol)) with (L)-homo-phenylalanine 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-(D)-phenylalanyl-(L)-homo-phenylalanine; FAB-MS m/e 473 (M+H)+.
