الإجراء التجريبي

To a solution of 1.60 g (6.17 mmol) of 4-[3-(N-2-pyridylmethylamino)propylthio)pyridine and 1.05 ml (7.40 mmol) of triethylamine in 10 ml of methylene chloride, 0.86 ml (7.40 mmol) of benzoyl 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 then the solvent was distilled off. The residue was purified by column chromatography (eluent: ethyl acetate/methanol=10:1) to obtain 1.32 g of the desired compound (yield: 58.9%, yellow oil).
