Reaction Steps

4-Bromo-3,5-difluoroaniline (10.5 g, 50.5 mmol) is dissolved in DMF (100 mL). NCS (28.6 g, 50.5 mmol) is added portionwise at room temperature. After 48 hours, the reaction is diluted with Et2O and washed with brine. The separated organic phase is dried (Na2SO4) and concentrated to give an oil. The residue is purified by column chromatography (EtOAc/hexanes) to give 4-bromo-2-chloro-3,5-difluoroaniline.
