반응 단계

To a solution of 4-bromo-3,5-dimethylphenol (10.1 g, 50.0 mmol) in pyridine (13 mL) was added acetic anhydride (7.66 g, 38.6 mmol), and the mixture was stirred at 50° C. for 30 min. The reaction mixture was ice-cooled, diluted with 0.5 M hydrochloric acid, and extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give the title compound (12.1 g, yield 99%) as a yellow oil.
