실험 절차

Add benzoyl peroxide (308 mg, 1.27 mmol) to a mixture of methyl-3-chloro-4-metylbenzoate (4.7 g, 25.5 mmol) and N-bromosuccinimide (4.98 g, 28.00 mmol) in anhydrous carbon tetrachloride (100 mL). Reflux the reaction mixture for 4 hrs and cool to room temperature. Filter the reaction mixture and concentrate the filtrate to provide the title compound as a crude oil (7.6 g, 28.8 mmol). MS (m/z): 264 (M+1).
