실험 절차

To a solution of (3-(benzyloxy)-4-methylphenyl)methanol (entire amount) in DMSO (15 mL) was added 2-iodoxybenzoic acid (3.20 g), and the mixture was stirred at room temperature for 2 hr. Ethyl acetate (250 mL) was added to the reaction mixture, and the insoluble material was filtered off. The filtrate was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (2.50 g) as a yellow oil.
