Sodium Carbonate → 2-[4-(10-[1,1';3',1'']Terphenyl-5'-yl-anthracen-9-yl)-phenyl]-imidazo [1,2-a] pyridine

Participants

Reaction Steps

Two point five grams (5.5 mmol) of 2-[4-(10-bromo-anthracen-9-yl)-phenyl]-imidazo [1,2-a] pyridine, 1.6 g (5.8 mmol) of [1,1′;3′,1″] terphenyl-5′-boronic acid and 0.13 g of tetrakis (triphenylphosphine) palladium were dissolved into 20 milliliter of 1,2-dimethoxyethane, and adding 9 milliliter of 2.0M sodium carbonate aqueous solution, the resultant suspension was refluxed under heating for 8 hours. After completion of the reaction, separation with filtration was carried out and resultant crystals were washed with water and methanol, thereby obtaining 2.4 g of yellowish white solids (yield: 71%). As a result of mass spectrum (MS) analysis, the yellowish white solids were identified as the aimed substance, and it was recognized that m/e=598 for molecular weight of 598.24.
