Reaction Conditions

Reaction Steps

In a 2000 ml two neck round bottom flask, 250 g of triphenylamine and 1000 ml of N,N′-dimethylformamide were charged, and the mixture was dissolved by heating to 40° C. A solution (450 ml) prepared by dissolving 190 g of N-bromosuccinimide in N,N′-dimethylformamide was slowly added dropwise using a dropping funnel at room temperature with vigorously stirring and, after the completion of the dropwise addition, the reaction was continuously performed for 1 hour. After the completion of the reaction, 1 ml of water was introduced in the reaction solution and the solvent was removed under reduced pressure. Then, 500 ml of water was added to deposit a product. The deposit was filtered, dried under reduced pressure and then purified by distillation under reduced pressure to obtain 100 g of N-(4-bromophenyl)-N-phenyl-aminobenzene.
