Vorschrift

1.0 g (2.9 mmol) of 1-(4-bromophenyl)-2-phenyl-1H-benzimidazole, 1.2 g (3.2 mmol) of 9,10-diphenylanthracene-2-boronic acid, and 0.067 g (0.058 mmol) of tetrakis(triphenylphosphine)palladium were dissolved into 20 mL of 1,2-dimethoxyethane. Then, 10 mL of a 2 M aqueous solution of sodium carbonate were added, and the whole was refluxed under heating for 8 hours in an argon atmosphere. After the completion of the reaction, the resultant was filtered, and the resultant solid was washed with water, methanol, and toluene to obtain 1.6 g of a greenish white solid (90% yield). Mass spectral analysis confirmed that the solid was a target product. The solid had an m/e of 598 with respect to a molecular weight of 598.24.
