Reaction Steps
To a solution of 2-tert-butylphenol (250 g, 1.67 mol) in CH3CN (1500 mL) was added NBS (300 g, 1.67 mol) at room temperature. After addition, the mixture was stirred at room temperature overnight and then the solvent was removed. Petroleum ether (1000 mL) was added, and the resulting white precipitate was filtered off. The filtrate was concentrated under reduced pressure to give the crude 2-tert-butyl-4-bromophenol (380 g), which was used without further purification.
