실험 절차

5-Methyl-2-nitrobenzoic acid methyl ester (27.1 g, 138.8 mmol) was dissolved in carbon tetrachloride (500 mL), and N-bromosuccinimide (29.6 g, 166.6 mmol) was added, followed by benzoyl peroxide (6.72 g, 27.7 mmol). The mixture was illuminated and gently refluxed for 4 hours. Then, the mixture was cooled and concentrated, then purified by column chromatography silica gel 230-400 mesh; 10% ethyl acetate in hexanes as eluent) to give 5-bromomethyl-2-nitrobenzoic acid methyl ester. Yield: 17.9 g (47%).
