Vorschrift

8.0 g (45 mmol) of N-bromosuccinimide and 10.0 g (41 mmol) of triphenylamine were placed in a 200 mL three-neck flask and then 150 mL of N,N-dimethylformamide was added. The mixture were stirred overnight at room temperature. N,N-dimethylformamide was removed, and the obtained solid was extracted with carbon tetrachloride. The solvent was removed, and the crude product was twice recrystallized from ethanol. As a result, a white solid of 4-bromotriphenylamine was obtained in an amount of 8.2 g (61.7%).
