Toluene → 3-Bromo-9-phenylcarbazole

참여 물질

반응 단계

In a 1000 mL conical flask were added 24 g (100 mmol) of 9-phenyl-9H-carbazole, 18 g (100 mmol) of N-bromo succinimide, 450 mL of toluene, and 200 mL of ethyl acetate, and this solution was stirred at room temperature for 45 hours. After the stirring, the obtained mixture was washed with water, and then magnesium sulfate was added therein for drying. When this mixture was filtered and the obtained filtrate was concentrated and dried, 32 g of a brown oily substance of 3-bromo-9-phenylcarbazole, which was the object of the synthesis, was obtained in a yield of 99% (synthesis scheme (X-6)).
