Reaction Steps

To a solution of 1-(4-methoxy-2,6-dimethylphenyl)ethanone (5.7 g, 32 mmol) in acetonitrile (64 mL) was added tetrabutylammoniumtribromide (TBABr3, 15.4 g, 32.0 mmol). The reaction was stirred at room temperature for 80 min. The solution was concentrated under reduced pressure, added with water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous MgSO4(s), and concentrated under reduced pressure to give 2-bromo-1-(4-methoxy-2,6-dimethylphenyl)ethanone (9.14 g), which was used directly for the next step without further purification.
