Benzoyl Peroxide → 1-(Bromomethyl)-2-fluoro-3-nitrobenzene

Participants

Reaction Steps

Benzoyl peroxide (10.7 g, 44 mmol) was added under reflux under nitrogen atmosphere to a solution of 2-fluoro-1-methyl-3-nitrobenzene (compound 2a-1) (68.2 g, 440 mmol) and N-bromosuccinimide (95.0 g, 528 mmol) in carbon tetrachloride (1500 mL), and the mixture was stirred under reflux for 5 hours. Impurities were then removed by filtration, and a crude product was obtained by vacuum concentration. It was then purified by column chromatography (hexane), and the title compound (68.7 g, 65%) was obtained as a yellow to light brown oil.
