Mode opératoire

A mixture of 1.5 g of 4-bromo-3-fluorobenzotrifluoride, 0.46 ml of ethanethiol, 851 mg of potassium carbonate and 2 ml of DMF was stirred at 75° C. for 2.5 hours. Water was poured to the cooled reaction mixture, and the mixture was extracted with t-butyl methyl ether. The organic layer was washed with water, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The resulting residue was applied to a silica gel column chromatography to obtain 1.15 g of 4-bromo-3-ethylsulfanylbenzotrifluoride.
