Potassium Carbonate → HCID 58480007, compound

Participants

Reaction Steps

9.4 g (22.0 mmol) of 2-(3,5-dibromophenyl)-1-phenyl-1H-benzo[d]imidazole according to Synthesis Example 3, 2.7 g (22.0 mmol) of pyridine-3-boronic acid, 0.76 g (3 mol %) of tetrakis(triphenylphosphine)palladium (0), and 6.1 g (44.0 mmol) of potassium carbonate were dissolved in 300 ml of tetrahydrofuran/H2O mixed in a volume ratio of 2/1. The solution was reacted at 80° C. for 12 hours. The acquired reactant was extracted with ethyl acetate and treated under reduced pressure to remove the solvent therein. The reactant was separated through a column and dried, obtaining 5.15 g (Y=54%) of a yellow solid.
