실험 절차
A mixture of 4-fluoro-2-methylbenzonitrile (2 g, 14.8 mmol), NBS (2.64 g, 15 mmol) and AIBN (100 mg) in CCl4 was refluxed under nitrogen for 2 hours. The reaction was cooled to room temperature. The solid was removed by filtration. The organic solution was concentrated to give crude product as an oil, which was used in the next step without further purification. 1H-NMR (400 MHz, CDCl3): δ 7.68 (dd, J=5.2, 8.4 Hz, 1H), 7.28 (dd, J=2.4, 8.8 Hz, 1H), 7.12 (m, 1H), 4.6 (s, 2H).
