الإجراء التجريبي

To a solution of 400 mg (1.21 mmol) of 4-[3-(N-benzylamino)propylthio] pyridine dihydrochloride and 0.55 ml (4.00 mmol) of triethylamine in 5 ml of methylene chloride, 0.17 ml (1.45 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) to obtain 0.22 g of the desired compound (yield: 50.4%, yellow oil).
