Participants

Conditions

Temperature: 120 °C

Procedure

5-Bromo-3-(2-cyanophenyl)-1-phenyl-1,2-dihydropyridin-2-one (100 mg), 60 mg of 2-nitrophenylboronic acid and 130 mg of cesium carbonate were suspended in 10 ml of dimethylformamide, then 20 mg of tetrakistriphenylphosphine palladium were added and the mixture was stirred at 120° C. in a nitrogen atmosphere for 4 hours. After allowing to cool, the reaction solution was poured into water, the mixture was extracted with ethyl acetate, the extract was dried over anhydrous magnesium sulfate, the solvent was evaporated in vacuo and the residue was purified by a silica gel column chromatography (hexane-ethyl acetate system) to give 35 mg of the title compound.
