The mixture was brought to reflux and azobisisobutyronitrile (213 mg, 0.1 eq.) was added. The mixture was maintained at reflux for 6 hours. The reaction was cooled to room temperature, concentrated and purified to give 1-Bromomethyl-2,6-dibromo-4nitrobenzene. 1H NMR (500 MHz, CDCl3) δ CHCl3: 4.81 (2H, s), 8.41(2H, s).
