실험 절차

To a solution of 1.62 g (6.24 mmol) of 4-[3-(N-2pyridylmethylamino)propylthio]pyridine and 1.10 ml (7.80 mmol) of triethylamine in 10 ml of methylene chloride, 0.51 ml (7.80 mmol) of acetyl chloride 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 the solvent was distilled off. The residue was purified by column chromatography (eluent: ethyl acetate/methanol=10:1) to obtain 1.61 g of the desired compound (yield: 85.6%, yellow oil).
