Procedure

Fifty grams (0.39 mole) of 2,6-difluoroaniline was treated with 71.0 g (0.39 mole) of N-bromosuccinimide in 250 ml of dimethylformamide by the procedure of Mitchell, Lai and Williams, J. Org. Chem., 44, 4733 (1979) to give a total yield of 50.2 g (62%) of 4-bromo-2,6-difluoroaniline, m.p.: 64°-66° C.
