Reaction Steps
To a solution of 2-methoxy-4-(trifluoromethoxy)benzaldehyde (1.0 g, 4.542 mmol) in dichloromethane (15 mL) was added m-chloroperoxybenzoic acid (2.04 g, 9.08 mmol). The resulting clear solution was stirred for 16 hours at room temperature. A white precipitate had formed and this was filtered off. The filtrate was evaporated to a white solid, which was diluted with ethyl acetate (25 mL) and washed with saturated aqueous sodium bicarbonate. The organic layer was dried over sodium sulphate, and evaporated to a white solid. This solid was redissolved in methanol (15 mL), and treated with triethylamine (2 mL, 10 mmol). After stirring for two hours, the solvents were evaporated. The residue was taken up in ethyl acetate (25 mL), and washed with 1N citric acid solution (20 mL) and brine (20 mL) dried over sodium sulphate, and evaporated to an oil. This crude material was then purified by eluting through a short pad of silica with dichloromethane, which afforded the title compound as a clear oil (650 mg, 57%)
