Procedure

In a mixture of 50 ml of acetic acid, 10 ml of water and 13 ml of nitric acid is dissolved 2 g (0.014 mole) of 3-chloro-2,4-difluorobenzoic acid and 3.64 ml (0.028 mole) of bromine. A solution of 3.52 g (0.0208 mole) of silver nitrate in 10 ml of water is then added slowly. After 14 hours at 20° C., the precipitate is filtered and rinsed with ether. The organic phase is washed with sodium bisulfite, then water and dried. Removal of the solvent affords the desired product.
