200 g of 2,3,4-trifluoro-benzotrifluoride in 500 ml of tetrahydrofuran are initially introduced into an autoclave, and 60 ml of liquid ammonia are injected. The batch is stirred at 130° C. (maximum pressure 18 bar) for 6 hours and then cooled and the pressure is released. At a boiling point of 92° -93° C./26 mbar, 92 g of 2,3-di- fluoro-4-trifluoromethylaniline are obtained by distillation.
