To a solution of 2,6-Difluorophenol (10.0 g, 76.86 mmol) in DMF (60 mL), N-bromosuccinimide (13.68 g, 76.86 mmol) was added at 0° C. and stirred at RT for 20 h. The reaction mixture was concentrated, diluted with water and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated under reduced pressure to afford 4-Bromo-2,6-difluorophenol as a light yellow liquid (15.1 g, 93 percent yield). 1H-NMR (δ ppm, DMSO-D6, 400 MHz): δ 10.49 (s, 1H), 7.35 (d, J=6.2 Hz, 2H).
