130 °C

To dry N,N-dimethylformamide (10 ml) were added 2-methoxyphenol (150 mg), 2,2,2-trifluoroethyl iodide (584 mg) and potassium carbonate (400 mg), and the mixture was stirred vigorously at 130° C. for 6 hours. To the reaction mixture was added water, and the mixture was extracted with diethyl ether. The extract was washed with water, dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by medium pressure liquid column chromatography on silica gel using a mixture of hexane and chloroform (5/2) as eluent to give 179 mg of 1-methoxy-2-(2,2,2-trifluoroethoxy) benzene as an oil.
