실험 절차

To a solution of 102 g (0.55 mole) of methyl (4-chlorophenyl)acetate in 100 ml of carbon tetrachloride was added 97.9 g (0.55 mole) of N-bromosuccinimide. The resulting mixture was refluxed and irradiated with a 500 W bromo lamp for 5 hours. It was then cooled, filtered, and the filtrate was evaporated to dryness to give 150 g (103% yield) of methyl (4-chlorophenyl)bromoacetate.
