Reaction Steps
To a solution of 2-chloro-4-methoxypyridine (786 mg) in toluene (10 mL) were added phenylmethanethiol (683 mg), N,N-diisopropylethylamine (1.56 g), tris(dibenzylideneacetone)dipalladium(0) (202 mg) and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (256 mg), and the mixture was stirred at 80° C. for 26 hr under an argon atmosphere. 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→hexane-ethyl acetate=19:1) to give the title compound as an orange oil (yield 454 mg, 38%).
