18.18 g (81.3 mmol) of 3-fluorantheneboronic acid, 22.99 g (81.3 mmol) of 3-bromoiodobenzene, 4.70 g (4.10 mmol) of tetrakis(triphenylphosphine)palladium (0), 80 ml of toluene, 80 ml of dimethoxyethane and 123 g of a 2M sodium carbonate aqueous solution were combined under argon atmosphere, and the mixture was stirred for 8 hours with refluxing and heating. After finishing the reaction, water was added to the reaction mixture, and the mixture was stirred at room temperature for one hour. Methanol was added thereto, and a solid matter was obtained by filtering, and it was refined by silica gel chromatography to obtain 20.43 g (yield: 70.4%) of 3-(3-bromophenyl)fluoranthene.
