To a solution of methyl iodide (59.0 g, 0.41 mol) in DMF (150 mL) was added potassium carbonate (23.0 g, 0.16 mol). 2-(Trifluoromethoxy)thiophenol (16.0 g, 0.08 mol) was added in portions during 30 min. The reaction mixture was then stirred vigorously overnight. Water (250 mL) was added. The reaction mixture was extracted with ethyl acetate (2×150 mL). The combined organic phases were washed with a 50% saturated aqueous solution of sodium chloride (4×100 mL), dried (magnesium sulphate), and concentrated in vacuo to give 15.0 g of 1-methylsulfanyl-2-trifluoromethoxybenzene.
