Azobisisobutyronitrile → HCID 12668053, compound

Participants

Reaction Steps

To a stirred solution 4-Chloro-2-methyl-benzonitrile 1(5.0 g, 33.0 mmol) in carbon tetrachloride (150 mL) was added N-bromosuccinamide (7.6 g, 42.9 mmol) and 2,2′-azobisisobutyronitrile (cat.). The reaction mixture was refluxed 6 hrs, filtered, concentrated, and partitioned between ether and water. The ether layer was dried, concentrated, and purified by silica gel chromatography (10% ether/hexanes) to yield a white solid (40%). 1H NMR (400 MHz, CDCl3) δ7.61 (d, J=8.3 Hz, 1 H, Ar), 7.57 (d, J=2.2 Hz, 1 H, Ar), 7.41 (dd, J=8.3, 2.0 Hz, 1 H, Ar), 4.59 (s, 2 H, CH2).
