Commercially available 3-methylbenzophenone (4.00 g, 20.4 mmol) was dissolved in carbon tetrachloride (100 mL), and N-bromosuccinimide (4.71 g, 26.5 mmol) and 2,2′-azobisisobutyronitrile (1.00 g, 6.09 mmol) was added to the solution, followed by stirring at 75° C. for 6.5 hours. After the reaction mixture was cooled, the precipitates were filterd out. The filtrate was combined and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:20) to obtain 3-bromomethylbenzophenone (4.31 g, yield 77%).
