実験手順

A stirred solution of 1-bromo-2-methyl-6-nitrobenzene (16.2 g, 0.075 mole) in 200 ml of carbon tetrachloride was irradiated and heated at reflux with a 250 watt brooder lamp. N-bromosuccinimide (13.5 g, 0.075 mole) was added to the refluxing reaction mixture, and the mixture was stirred for approximately 23 hours. The mixture was cooled, filtered, and washed with two 200 ml portions of saturated aqueous sodium chloride solution. The organic phase was passed through phase separation filter paper. The filtrate was evaporated under reduced pressure to give 2-bromo-1-bromomethyl-3-nitrobenzene (20 g).
