A mixed solution of 7.0 g of 1-bromopyrene, 4.7 g of 2-naphthaleneboronic acid, 11.6 g of tripotassium phosphate, 1.8 g of tetrabutylammonium bromide, 0.11 g of palladium acetate and 248 ml of dimethylformamide was heated with stirring under a nitrogen gas flow at 130° C. for 5 hours. After cooling the solution to room temperature, 300 ml of water was injected, followed by stirring at room temperature for 0.5 hours. The precipitated solid was collected by filtration and then washed twice with 100 ml of water. The resultant solid was dissolved in 200 ml of dichloromethane, dried over magnesium sulfate, evaporated and then filtered using Celite. The filtrate was evaporated and the residue was washed twice with 100 ml of methanol, and then the precipitated solid was collected by filtration. The solid was vacuum-dried to obtain 7.5 g of 1-(2-naphthyl)pyrene.
