In a stream of argon, 20 g (55.6 mmol) of 1,6-dibromopyrene, 16.3 g (133 mmol) of phenyl boronic acid, 2.5 g (4 mol %) of tetrakistriphenylphosphine palladium, an aqueous solution containing 26.5 g (65 mmol) of sodium carbonate in 125 mL of water, and 250 mL of toluene were added to a 1-L three-necked flask equipped with a cooling pipe, and the whole was refluxed under heat at 100° C. for 8 hours. After the completion of the reaction, 50 mL of water was added and then a crystal was filtered out, washed with 50 mL of water, 100 mL of ethanol, and 100 mL of toluene. As a result, 15.3 g of 1,6-diphenylpyrene (a white powder) was obtained (99% yield).
