Benzoyl Peroxide → 7-(Bromomethyl)-4-chloroquinoline-2-carbonitrile

Participants

Reaction Steps

To a solution of 4-chloro-7-methylquinoline-2-carbonitrile (6.66 g, 33 mmol) in CCl4 (160 mL) was added NBS (6.46 g, 36.3 mmol) and benzoyl peroxide (800 mg, 3.3 mmol). The mixture was heated under reflux overnight, cooled to room temperature and evaporated to dryness. The reaction mixture was purified by flash chromatography on silica gel (eluting solvent: dichloromethane/hexane, 9/1) to provide the title compound (8.46 g). 1HNMR (400 MHz, acetone-d6): δ 8.37 (d, 1H), 8.30 (s, 1H), 8.20 (s, 1H), 8.05 (d, 1H), 4.95 (s, 2H).
