Procedure

A −78° C. solution of 2-fluoro-6-iodo-3-methoxybenzonitrile (148 mg, 0.53 mmol) in dichloromethane (5 mL) was treated dropwise with BBr3 (2.5 mL, 1M in dichloromethane, 2.5 mmol), warmed to room temperature, stirred for 18 hours, poured into water, and extracted with diethyl ether. The extract was dried (MgSO4), filtered, and concentrated. The residue was purified by flash column chromatography on silica gel with 20% ethyl acetate/hexanes to provide 110 mg of the desired product. MS (ESI(−)) m/e 262 (M−H)−.
