Методика

To a solution of 1.00 g (4.15 mmol) of 4-(3-aminopropylthio)pyridine dihydrochloride and 2.77 ml (19.8 mmol) of triethylamine in 40 ml of methylene chloride was added 846 mg (4.96 mmol) of 4-anisoyl chloride under ice-cooling with stirring and the mixture was stirred for at room temperature for 30 minutes. The reaction mixture was washed with an aqueous saturated sodium bicarbonate solution and water and dried. The solvent was distilled off. The residue was purified by column chromatography (eluent: ethyl acetate) to obtain the powder which was washed with ether and dried to obtain 990 mg of the desired compound (78.9%, colorless powder), mp: 121.0°-122.0° C.
