130 °C

A mixed solution of 2 g of 1,6-dibromopyrene, 1.9 g of 4-methylphenylboronic acid, 5.9 g of tripotassium phosphate, 0.9 g of tetrabutylammonium bromide, 15 mg of palladium acetate and 30 ml of dimethylformamide was heated with stirring under a nitrogen gas flow at 130° C. for 6 hours. After cooling the solution to room temperature, 30 ml of water was injected, followed by filtration. The resultant solid was washed with 30 ml of ethanol, recrystallized from toluene and then vacuum-dried to obtain 1.3 g of 1,6-bis(4-methylphenyl)pyrene.
