Vorschrift

An amount of 2.46 g (8.26 mmol) of 10-phenylanthracene-9-boronic acid synthesized in the same manner as in Exemplary Synthesis 2, 9.75 g (41.3 mmol) of p-dibromobenzene, and 250 mg of tetrakis triphenylphosphine palladium as catalysis were dissolved in a mixed solvent of 60 ml of toluene and 15 ml of ethanol. Then, 30 ml of 2M sodium carbonate solution was added and allowed to react at 90° C. for 12 hours. After the reaction was completed, the organic layer was separated and purified by column chromatography to obtain 1.48 g (3.62 mmol) of 9-phenyl-10-(4-bromophenyl)anthracene. The yield was 43.8%.
