Reaction Steps

To a solution of methyl 3-hydroxy-4-(trifluoromethyl)benzoate (see WO 2007/129745) (2.00 g) in N,N-dimethylformamide (9.00 mL), sodium hydride (60% dispersion in mineral oil, 545 mg) was added in small portions under cooling with ice. After stirring the mixture at room temperature for 30 minutes, methyl iodide (0.849 mL) was added. After stirring the reaction mixture at room temperature for 2.5 hours, iced water was added and two extractions were conducted with ethyl acetate. The combined organic layers were washed with water three times and thereafter dried over anhydrous magnesium sulfate. After removing the desiccant by filtration, the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=95:5-85:15) to give methyl 3-methoxy-4-(trifluoromethyl)benzoate as a colorless solid (2.11 g).
