Benzyl mercaptan → 3-Methyl-2-(phenylmethylthio)-pyridine

Participants

Reaction Steps

To a suspension of sodium hydride (60% in oil, 1.44 g) in tetrahydrofuran (45 mL) was added dropwise phenylmethanethiol (465 mg) at room temperature and the mixture was stirred for 15 min. 2-Bromo-3-methylpyridine (2.0 g) was added to the reaction mixture, and the mixture was stirred at 60° C. for 1.5 hr. The reaction mixture was diluted with water, and concentrated under reduced pressure. The residual aqueous layer was extracted twice with ethyl acetate. Combined organic layers were washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent:hexane-hexane-ethyl acetate=97:3) to give the title compound as a gray oil (yield 1.79 g, 72%).
