Potassium Carbonate → HCID 10273711, compound

Participants

Reaction Steps

150 mg of 1-(3-aminophenyl)-3-(2-cyanophenyl)-5-(2-pyridyl)-1,2-dihydropyridin-2-one and 63 mg of ammonium thiocyanate were added to 2 ml of acetic acid. The mixture was stirred at room temperature for 1 hour, to which 0.022 ml of bromine was added, and further stirred for 1 hour. The reaction mixture was distributed into the ethyl acetate and water layers, and neutralized with 20% aqueous solution of potassium carbonate. The organic layer was washed with water, dried and concentrated, and the residue was refined by silica gel chromatography (ethyl acetate/hexane-based solvent), to obtain 58 mg of the subject compound.
