In argon atmosphere, a mixture of 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 2 M sodium carbonate aqueous solution was refluxed for 8 h under stirring. After the reaction, the reaction mixture was added with water and stirred at room temperature for one hour. After adding methanol, the solid matter was collected by filtration and purified by silica gel chromatography to obtain 20.43 g (yield: 70.4%) of 3-(3-bromophenyl)fluoranthene.
