Reaction Steps
A mixture of 4-methyl-2-phenylbenzoic acid methyl ester (2.26 g, 10 mmol), prepared as in Example 227B, N-bromosuccinimide (1.87 g, 10.5 mmol) and 2,2′-azobisisobutyronitrile (25 mg) in carbon tetrachloride (40 mL) was stirred at reflux for 7 hours. The reaction mixture was poured into ethyl acetate and extracted with water (2×), aqueous sodium hydrogen sulfite and brine, dried, filtered, and concentrated in vacuo. Chromatography on silica gel (10% ethyl acetate-hexane) gave 4-bromomethyl-2-phenylbenzoic acid methyl ester (2.57 g, 84%).
