Procedure

A mixture of 3-methoxyphenol (600 mg, 4.83 mmol) and N-iodosuccinimide (1.09 g, 4.84 mmol) was dissolved in anhydrous N,N-dimethylformamide (25 mL), and the mixture was stirred at room temperature overnight. Ethyl acetate (100 mL) and diethylether (100 mL) were added. The organic layer was washed with 1% aqueous sodium thiosulfate solution (200 mL), water (100 mL), and saturated brine (50 mL), dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled reference compound (167 mg) as a colorless oil. (Yield 14%)
