6-Bromo-2-naphthol (500 mg, 2.242 mmol, 1 eq) and NBS (558.7 mg, 3.319 mmol, 1.4 eq) are stirred at RT in 4.4 ml of acetone and 22 μl of 1 N HCl for 15 min. Ethyl acetate is added, and this organic phase is washed three times with 1 N HCl. After drying over magnesium sulfate, filtering and concentrating in vacuum on a rotary evaporator, the desired product is obtained in quantitative yield (677 mg).
