N-bromobutanimide → 4-Bromo-1-(bromomethyl)-2-(trifluoromethyl)benzene

Participants

Reaction Steps

N-Bromosuccinimide (2.6 g) and 2,2′-azobis(isobutyronitrile) (35 mg) were added to a solution of 5-bromo-2-methylbenzotrifluoride (CAS #86845-27-4, 3.5 g) in carbon tetrachloride (35 mL), and the mixture was heated under reflux for five hours. The reaction solution was ice-cooled and then the insoluble matter was removed by filtration. The filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (carrier: Wakogel C-200; elution solvent: heptane) to obtain 3.86 g of the title compound. The property values of the compound are as follows.
