Versuchsvorschrift

1.57 g (3.78 mmoles of H-Nle-Asp-D-Phg-NH2.HCl are reacted with 1.52 g (3.78 mmoles) of BOC-Trp-OSu in 50 ml of DMF in the presence of 1.06 ml (7.6 mmoles) of triethylamine. Next day the reaction mixture is evaporated in vacuo, the residue is admixed with water, and the suspension is filtered. 2.45 g (97.5%) of BOC-Trp-Nle-Asp-D-Phg-NH2 are obtained; m.p.: 217° C. (decomposition), Rf5 :0.35, [α]D -32.7° (c: 1.0, in dimethyl formamide).
