Reaction Steps

A mixture of 2-fluoro-5-nitrobenzotrifluoride (2.09 g. 10 mmol) and sodium methanesulfinate (1.32 g, 1.1 mmol) in DMSO (20 mL) was heated at 130° C. for 17.5 hours. After cooling down to room temperature, the mixture was poured into ice-water. The whole was extracted with ethyl acetate (30 mL×2), the combined organic layer washed with water, brine, dried over MgSO4, and concentrated in vacuo. The residue was crystallized from hexane to give the subtitle compound (1.56 g, 57.8%, yield).
