80 °C

To a solution of 4-methoxy thiophenol (5 mL, 40.7 mmol) and methyl-3-nitro-4-chlorobenzoate (10.52 g, 48.8 mmol) in DMF (40 mL) was added CsCO3 (26.5 g, 81.4 mmol) and the reaction mixture heated at 80° C. for 3 hours. After cooling, the solution was poured into water and extracted with ethyl acetate (3×100 mL). The combined organic layers were dried over MgSO4, filtered, and concentrated under vacuum to afford the title compound after chromatography on silica gel using ethyl acetate/hexanes as eluent (10.93 g, 80%).
