実験手順

4-aminothiophenol (10 g) was dissolved in methanol (200 ml), aqueous solution of sodium hydroxide (15.7 g, 60 ml) was added to the mixture, 3-(chloromethyl)pyridine hydrochloride (14.4 g) was added to the mixture at 0° C., and the mixture was stirred for 2 hours at room temperature. The solvent was removed under reduced pressure, and the obtained residue was added to water, and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure and the obtained residue was washed with hexane/ethyl acetate, to give 4-[(3-pyridinylmethyl)sulfanyl]aniline (13.1 g).
