Versuchsvorschrift

To a solution of 4-bromo-3-(trifluoromethyl)aniline (64 g, 267 mmol) in Et2O (500 mL) was added an HCl solution (1 M in Et2O; 300 mL) dropwise and the resulting mixture was stirred at room temp. for 16 h. The resulting pink-white precipitate was removed by filtration and washed with Et2O (50 mL) and to afford 4-bromo-3-(trifluoromethyl)aniline HCl salt (73 g, 98%).
