실험 절차

To a solution of 396 mg (1.64 mmol) of 4-(3-aminopropylthio)pyridine dihydrochloride and 0.27 ml (1.97 mmol) of triethylamine in 20 ml of methylene chloride, 500 mg (1.96 mmol) of 3-quinolineacryloyl chloride hydrochlride was added under ice-cooling with stirring. The mixture was stirred at room temperature for 30 minutes. The reaction mixture was washed with a saturated aqueous solution of sodium bicarbonate and water and dried, and then the solvent was distilled off. The residue was purified by column chromatography (eluent: methanol/ethyl acetate=1:10) to obtain powder. The powder was washed with ether and dried to obtain the desired compound (480 mg, yield: 83.8%, pale yellow powder).
