A solution of 7-chloro-3-methyl-4-oxo-1-phenyl-1,4-dihydro-quinoline-2-carboxylic acid methyl ester (1.6 g, 4.88 mmol), N-bromosuccinimide (869 mg, 4.88 mmol) and benzoyl peroxide (118 mg, 488 μmol) in carbon tetrachloride (50 mL) was heated at 100° C. for 5 h. At this time, the reaction was cooled to 25° C. The resulting solids were collected by filtration to afford 3-bromomethyl-7-chloro-4-oxo-1-phenyl-1,4-dihydro-quinoline-2-carboxylic acid methyl ester (1.7 g, 85.6%) as a white solid. The material was used without further purification.
