Versuchsvorschrift

To a stirred mixture of 6-hydroxy-1,2,3,4-tetrahydro-isoquinoline-7-carbaldehyde hydrobromide (82 mg, 0.46 mmol) and triethylamine (322 μL, 234 mg, 2.3 mmol) in anhydrous tetrahydrofuran (2 mL), 3-(4-methyl-piperazin-1-yl)-propionic acid (80 mg, 0.46 mmol), (3-dimethylamino-propyl)-ethyl-carbodiimide hydrochloride (98 mg, 0.51 mmol) and 1-hydroxybenzotriazole (69 mg, 0.51 mmol) were added in the above order and the mixture was stirred at room temperature for 7 h. After evaporation, the residue was taken up in chloroform (10 mL) and washed with sat NaHCO3 (2×5 mL) and brine (5 mL). The organic phase was dried over MgSO4 and evaporated. The obtained crude product (94 mg) was purified by column chromatography on silica gel, eluting with CHCl3/MeOH 94/6 mixture. In this manner the title compound (33 mg, 0.10 mmol, 21%) was obtained.
