Mode opératoire

Into a 200 ml three-necked flask, 8.0 g (45 mmol) of N-bromosuccinimide and 10.0 g (41 mmol) of triphenylamine were placed, followed by 150 ml of N,N-dimethylformamide. The mixture was stirred overnight at room temperature. Next, N,N-dimethylformamide was removed from the reaction, and the resulting solid matter was extracted with carbon tetrachloride. Then, carbon tetrachloride was removed, and the reaction product was recrystallized twice from ethanol to give a white solid, 4-bromotriphenylamine in an amount of 8.2 g (yield: 61.7%).
