Sodium Carbonate → 2-[4-[10-(2-Naphthalenyl)-9-anthracenyl]phenyl]-1-phenyl-1H-benzimidazole

Participants

Reaction Steps

Dissolving 4.0 g (11 mmol) of 2-(4-bromophenyl)-1-phenyl-1H-benzimidazole, 4.0 g (11 mmol) of 10-naphthalene-2-yl-anthracene-9-boronic acid and 0.27 g of tetrakis (triphenylphosphine) palladium into 40 milliliter of 1,2-dimethoxyethane, adding 18 milliliter of 2.0M sodium carbonate aqueous solution, the resultant suspension was refluxed with heating for 7 hours. After completion of the reaction, separation with filtration was carried out and resultant crystals were washed with water and methanol, thereby obtaining 5.1 g of yellowish white solids (yield: 78%). As a result of mass spectrum (MS) analysis, it was recognized that the yellowish white solids were identified as the aimed substance and that m/e=572 for molecular weight of 572.23.
