실험 절차

2-chloro-1-methyl-3-nitrobenzene (1 g, 5.8 mmol) was dissolved in CCl4 (10 mL), then N-bromosuccinimide (2.28 g, 12.8 mmol) and benzoyl peroxide (846 mg, 3.5 mmol) were added. The mixture was stirred overnight at reflux. The solid was removed by filtration, and the filtrate was washed with water and dried over sodium sulfate. After evaporation of the solvent, the residue was dissolved in DCM and purified on silica gel using 30% hexane/AcOEt to afford 1-(bromomethyl)-2-chloro-3-nitrobenzene (686 mg, 47% yield); 1H NMR (400 MHz, CDCl3): δ 4.64 (s, 2H), 7.42 (t, J=7.9 Hz, 1H), 7.67 (dd, J=1.6 Hz, J=7.9 Hz, 1H), 7.75 (dd, J=1.6 Hz, J=7.9 Hz, 1H).
