300 mg (1.35 mmol) of 3-fluoro-2-methyl-4-trifluoromethylbenzoic acid were initially charged in 5 ml of N,N-dimethylformamide, and 59 mg (purity 60% by weight, 1.49 mmol) of NaH were added. The mixture was stirred for 10 min, and 199 mg (purity 95% by weight, 2.70 mmol) of sodium thiomethoxide were then added. The mixture was stirred at RT for 1.5 h and then heated at 80° C. for 16 h. The reaction mixture was cooled and, for workup, poured into water and extracted with ethyl acetate, and the aqueous phase was then acidified with concentrated HCl. The mixture was extracted twice with t-butyl methyl ether, dried and concentrated. This gave 310 mg of the product.
