Versuchsvorschrift

To a solution of 1.0 g (3.87 mmol) of 4-[3-(N-benzylamino)propylthio)-pyridine and 0.65 ml (4.64 mmol) of triethylamine in 25 ml of methylene chloride, 0.49 ml (4.64 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 then the solvent was distilled off. The residue was purified by column chromatography (eluent: chloroform/methanol=25:1) to obtain 980 mg of the desired compound (yield: 84.2%, yellow oil).
