実験手順

To a suspension of 3-chloro-2-methylbenzoic acid methyl ester (5.62 g, 30.4 mmol), and N-bromosuccinimide (5.94 g, 33.4 mmol) in carbon tetrachloride (200 mL) was added benzoyl peroxide (800 mg, 3.30 mmol). The resulting suspension was immersed in an oil bath held at 85° C., and illuminated with a 300W halogen worklight. After stirring for 16 hours with heat and illumination the reaction mixture was allowed to cool to ambient temperature, filtered to remove the insoluble succinimide, and concentrated under reduced pressure to afford 2-bromomethyl-3-chlorobenzoic acid methyl ester as a yellow semi-solid. This crude material was carried on to the next step without purification.
