130 °C

A mixed solution of 4 g of 1,6-dibromopyrene, 3.8 g of 4-methylphenylboronic acid, 12 g of tripotassium phosphate, 2 g of tetrabutylammonium bromide, 30 mg of palladium acetate and 60 ml of dimethylformamide was heated and stirred under a nitrogen gas stream at 130° C. for 6 hours. The solution was cooled to room temperature and 60 ml of water was poured into the solution, followed by filtration. The resulting solid was washed with 60 ml of ethanol, recrystallized from toluene and then vacuum-dried to obtain 2.6 g of 1,6-bis(4-methylphenyl)pyrene.
