Under an argon atmosphere, 5.98 g of benzo[c]phenanthrene-5-boronic acid, 5.14 g of 2-bromoanthracene, 0.462 g of tetrakis(triphenylphosphine)palladium(0), 30 mL of 1,2-dimethoxyethane and 15 mL of a 2M aqueous solution of sodium carbonate was charged, and the mixture was refluxed with stirring for 8 hours. After cooling to room temperature, deposited crystals were separated by filtration. The resulting solids were recrystallized with toluene-hexane and washed repeatedly, whereby 6.07 g (yield: 75%) of 5-(2-anthryl)benzo[c]phenanthrene was obtained.
