Procedure

To a solution of the 1-chloro-4-methoxy-2-methylbenzene (2.0 g, 12.77 mmol) in anhydrous carbon tetrachloride (50 mL), NBS (2.29 g, 12.98 mmol) and benzoyl peroxide (0.154 g, 0.64 mmol) was added. The reaction mixture was heated to reflux overnight. Then, the reaction mixture was cooled to room temperature and filtered. The filtrate was evaporated to provide crude 2-(bromomethyl)-1-chloro-4-methoxybenzene, which was used for the next step without any further purification; 1H NMR (400 MHz, DMSO-d6): δ 3.74 (s, 3H), 4.66 (s, 2H), 7.01 (d, J=8.9 Hz, 1H), 7.19 (s, 1H), 7.38 (d, J=8.9 Hz, 1H).
