Versuchsvorschrift

In N,N-dimethylformamide (5 ml) was dissolved 3-(N-methylcarbamoyl)-1-[(6-trimethylsilylethynylbenzo[b]thien-2-yl)sulfonyl]piperazine (218 mg), followed by the addition of lithium 6-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine-2-carboxylate (188 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (240 mg) and 1-hyroxybenzotriazole (68 mg). The resulting mixture was stirred at room temperature for 30 minutes. The reaction mixture was diluted with methylene chloride, washed with water (twice) and then with a saturated aqueous solution of sodium bicarbonate. After drying over anhydrous sodium sulfate, the solvent was distilled off under reduced pressure. The residue was purified by chromatography on a silica gel column (methanol:methylene chloride=3:97→5:95→7:93), whereby the title compound (90 mg) was obtained. MS (FAB) m/z: 616 (M+H)+.
