실험 절차

In dichloromethane (10 ml), 6-(4-pyridyl)nicotinic acid hydrochloride (96 mg) and 1-[(6-chloronaphthalen-2-yl)sulfonyl]piperazine trifluoroacetate (150 mg) were suspended, followed by the addition of 1-hydroxybenzotriazole (48 mg) and N-methylmorpholine (155 μl). After the addition of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (102 mg) under ice cooling, the resulting mixture was stirred at room temperature for 16 hours. Owing to the slow reaction, N,N-dimethylformamide (10 ml) was added to the reaction mixture and the resulting mixture was stirred for 3 days. After completion of the reaction, the solvent was distilled off. The residue was purified by chromatography on a silica gel column (1% methanol-di-chloromethane). The solvent was then distilled off. To the residue, tetrahydrofuran and ethanolic 1N hydrochloric acid were added and the solid so precipitated was collected by filtration and dried, whereby the title compound (105 mg, 55%) was obtained as a colorless solid.
