Reaction Conditions

Reaction Steps

Next, a mixed solution of 40.0 g of 1-(4-methylphenyl)pyrene, 24.4 g of N-bromosuccinimide and 1.4 L of dimethylformamide was heated and stirred under a nitrogen gas stream at 40° C. for 7 hours. The solution was cooled to room temperature and 1.0 L of water was poured into the solution, followed by extraction with 500 ml of dichloromethane. The organic layer was washed twice with 200 ml of water, dried over magnesium sulfate and then filtered through Celite. The filtrate was evaporated and the residue was washed twice with 200 ml of ethyl acetate, and then the precipitated solid was collected by filtration and vacuum-dried to obtain 11.4 g of 1-bromo-6-(4-methylphenyl)pyrene.
