Методика

Into 500 ml of dry dimethylformamide, 50 g (200 mmole) of triphenylamine was dissolved. To the obtained solution, a solution prepared by dissolving 36 g (200 mmole) of N-bromosuccinimide into 100 ml of dry dimethylformamide was added and the obtained solution was stirred at the room temperature for 6 hours. After the reaction was completed, 1 liter of water was added to the reaction mixture and the formed precipitates were separated by filtration. The obtained light yellow solid was washed with water, dried at a reduced pressure and recrystallized from hexane and 38 g (the yield: 59%) of white needle crystals of the subject compound was obtained.
