실험 절차

The above oxime (3.76 g, 17.24 mmol) and copper (II) acetate (370 mg) were dissolved in acetonitrile (100 cm3) under nitrogen and heated under reflux. After 5 h, the mixture was evaporated, the residue taken into EtOAc, washed with sulfuric acid (1N), water, brine, dried (MgSO4) and evaporated to give 3-fluoro-5-bromobenzonitrile (3.08 g, 15.39 mmol, 89%) which was used without further purification.
