A stirred mixture of 36.9 g of methyl o-chlorophenylacetate, 36.0 g of N-bromosuccinimide, and 2 drops of 48% hydrobromic acid in 500 ml of carbon tetrachloride is refluxed for 20 hours and then filtered through magnesium silicate. Evaporation under reduced pressure gives methyl α-bromo-o-chlorophenylacetate as a straw-colored liquid.
