Reaction Steps

2-Fluoro-3-trifluoromethylaniline (28.8 g, 161 mmol) is dissolved in DMF (100 mL). A solution of NBS (28.6 g, 161 mmol) in DMF (100 mL) is added dropwise at room temperature. After 3 hours, the reaction is diluted with Et2O and washed with brine. The separated organic phase is dried (Na2SO4) and concentrated to give 4-bromo-2-fluoro-3-trifluoromethylaniline as an oil.
