Reaction Steps

To a solution of 3-bromo-5-methylpyridine (888 mg) in toluene (10 mL) were added phenylmethanethiol (705 mg), N,N-diisopropylethylamine (1.47 g), tris(dibenzylideneacetone)dipalladium(0)(189 mg) and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (239 mg), and the mixture was stirred under an argon atmosphere at 80° C. for 1.5 hr. The reaction mixture was filtered through silica gel, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent:hexane-ethyl acetate=19:1→17:3) to give the title compound as a yellow oil (yield 1.06 g, 95%).
