실험 절차
Place 2-bromo-1,3-dichloro-4-methylbenzene (50 g, 208 mmol) in carbon tetrachloride (400 mL). Add benzoyl peroxide (5 g, 20.8 mmol) and NBS (38.9 g, 219 mmol) and heat to 80° C. and stir for 16 hours. Cool reaction and filter. Dissolve in hexanes and wash with sodium bisulfate and then with sodium bicarbonate. Purify by distillation. Collect product at 135° C. under reduced pressure to give 43.5 g (65%) of 2-bromo-4-(bromomethyl)-1,3-dichlorobenzene.
