Sodium Hydroxide → 3-Chloro-4-[(3-pyridinylmethyl)sulfanyl]aniline

Participants

Reaction Steps

4-amino-2-chlorobenzenethiol (1.2 g) was dissolved in methanol (24 ml), and to this solution was added 3N aqueous solution of sodium hydroxide (7.5 ml) and then, 3-(chloromethyl)pyridine hydrochloride (1.48 g), and the mixture was stirred for 15 minutes at room temperature. The solvent was removed under reduced pressure, and water was added to the obtained residue, and the mixture was 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 purified by silica gel column chromatography, to give 3-chloro-4-[(3-pyridinylmethyl)sulfanyl]aniline (0.83 g).
