4.92 g (20 mmol) of pyrene-1-boronic acid, 5.94 g (21 mmol) of 3-bromoiodobenzene, and 0.46 g (0.4 mmol, 2 mol %) of tetrakis(triphenylphosphine)palladium(0) were loaded into a 300-ml three-necked flask, and air in the container was replaced with argon. Further, 10 ml of toluene and 30 ml (3 eq) of a 2M aqueous solution of sodium carbonate were added to the mixture, and the whole was refluxed under heat in an oil bath at 100° C. for 8 hours. After one night, the resultant was extracted with toluene/ion-exchanged water and purified by column chromatography, whereby 5.61 g of 3-pyrenylbromobenzene were obtained (79% yield).
