Sodium Carbonate → 5-(9,10-diphenylanthracen-2-yl)-1-methyl-2-phenyl-1H-benzimidazole

Participants

Reaction Steps

1.4 g (4.9 mmol) of 5-bromo-1-methyl-2-phenyl-1H-benzimidazole, 2.0 g (5.3 mmol) of 9,10-diphenylanthracene-2-boronic acid, and 0.11 g (0.097 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 2.0 g of a greenish white solid (76% yield). Mass spectral analysis confirmed that the solid was a target product. The solid had an m/e of 536 with respect to a molecular weight of 536.23.
