Procedure

1.5 mL of ethyl mercaptan was added to a mixture of 3.83 g of 2-fluoro-4-trifluoromethylbenzoic acid, 10 mL of NMP and 15 g of cesium carbonate, and the mixture was stirred at 60° C. for 4 hours. A saturated aqueous sodium bicarbonate solution was added to the cooled reaction mixture, and the mixture was extracted with ethyl acetate. Hydrochloric acid was added to the aqueous layer, and the precipitated solid was taken by filtration and dried under reduced pressure to obtain 4.6 g of 2-ethylsulfanyl-4-trifluoromethylbenzoic acid.
