Versuchsvorschrift

tert-Butyloxycarbonyl-L-tryptophan (3.00 g, 9.9 mmol) and 1,2,3,4-tetrahydroisoquinoline (1.31 g, 9.9 mmol) were suspended in THF (20 ml). At a temperature of 0° C., hydroxybenzotriazole (1.33 g, 9.9 mmol), diisopropylethylamine (1.27 g, 9.9 mmol), and EDC (N-3-dimethylaminopropyl-N′-ethylcarbodiimide hydrochloride, 1.89 g, 9.9 mmol) were added. The reaction mixture was stirred overnight at r.t. The solvent was evaporated, the residue was taken up in ethyl acetate, washed with water, and dried (Na2SO4). After evaporation of the solvent, the title compound, MS: m/e=420.5 (M+H+), (2.90 g, 70%) was obtained by chromatographic purification of the residue (silica gel, MeOH, CH2Cl2).
