Reaction Steps

2-Methyl-benzoic acid methyl ester (1.50 g 10 mmol), N-bromosuccinimide (1.96 g, 11 mmol) and 2,2′-azobis(2-methylpropionitrile) (AIBN) (25 mg, 0.15 mmol) were dissolved in chloroform (3 ml). The solution was heated at reflux for 16 h. cooled and the solvent evaporated in vacuo. The residue was purified by silica gel chromatography using a gradient of ethyl acetate/hexane (1–2%) as eluant. Pure fractions were collected and the solvent evaporated in vacuo affording 2.05 g (89%) of 2-bromomethyl-benzoic acid methyl ester as a solid.
