실험 절차

A mixture of 2-chloro-4-methyl-1-trifluoromethylbenzene 26 (0.20 g, 1 mmol), N-bromosuccinimide (0.17 g, 1 mmol) and benzoyl peroxide (7.4 mg, 0.03 mmol) in carbon tetrachloride (2 mL) was heated to reflux for 2 hours. Another portion of benzoyl peroxide (20 mg, 0.08 mmol) was added. The mixture was heated to reflux for another 0.5 hours. The reaction mixture was further stirred at room temperature for 16 hours. The solid was removed by filtration. The solvent was removed under reduced pressure. The crude product was purified by flash chromatography on silica, using petroleum ether as eluent, to give 0.22 g (80%) of Compound 27.
