Azobisisobutyronitrile → 1-(Bromomethyl)-4-nitro-2-(trifluoromethyl)benzene

Participants

Reaction Steps

Into a solution of 1-methyl-4-nitro-2-trifluormethylbenzene (4.1 g, 20 mmol) in carbon tetrachloride (30 mL) were added NBS (5.4 g, 30 mmol) and AIBN (493 mg, 3 mmol). The reaction was refluxed overnight and then partitioned with water. The organic layer was separated and the aqueous layer was extracted with CH2Cl2. The combined organic extracts were washed with water, dried over Na2SO4, filtered and concentrated to afford the material that was not purified but used directly in the next step.
