反应详情

A mixture of 3,4-difluoro-nitrobenzene (25 g, 0.157 mol) and sodium methanethiolate (10.5 g, 0.15 mol) was stirred at room temperature overnight. The reaction mixture was poured into water and extracted twice with ether. The extracts were combined, washed with water (twice) and brine, dried (sodium sulfate), filtered, evaporated, and purified by column chromatography, eluting with 17% dichloromethane/hexanes to give 2-fluoro-1-methylsulfanyl-4-nitro-benzene (18.6 g, 63%).
