実験手順

To a solution of 1.00 g (4.15 mmol) of 4-(3-aminopropylthio)pyridine dihydrochloride and 2.78 ml (19.9 mmol) of triethylamine in 40 ml of methylene chloride was added 0.93 ml (4.96 mmol) of 4-n-butylbenzoyl chloride under ice-cooling with stirring and the mixture was stirred at room temperature for 30 minute. 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 1.10 g of the desired compound (free base) (80.7% colorless wax), mp: 46.0°-47.0° C.
