Procedure

2-methoxy-4′-methylbiphenyl, 160 mg (0.81 mmol), NBS, 158 mg (0.91 mmol), and AIBN, 1 mg (0.006 mmol) were suspended in 7 mL tetrachloromethane, and refluxed for 24 hours. The product was filtered, and the solvent removed from the filtrate by rotary evaporation. Equal amounts of diethyl ether and water were added and the product extracted. The ether layer was separated and dried over MgSO4, filtered, and the solvent removed. 4-(2-Methoxyphenyl)benzyl bromide, 128 mg, was obtained as an oil.
