3,5-Di-t-butyltoluene (5 g), N-bromosuccinimide (4.79 g) and azobisisobutyronitrile (20 mg) were dissolved in carbon tetrachloride (30 ml) and the solution was heated at reflux for 3 h. When cool, a white solid was removed by filtration, and the filtrate was concentrated yielding a yellow oil, which was used without further purification. 1H NMR (360 MHz, CDCl3) δ1.30 (18H, s, CH3), 4.45 (2H, s, CH2), 7.2 (2H, d, J=1.75 Hz, ArH), 7.4 (1H, s, ArH).
