Participants

Reaction Steps

4-Phenyl-5,6-bis(p-methylphenyl)-2H-pyridazin-3-one (1.8 g) and 0.88 g of ethylene carbonate were charged to a flask in 100 ml dimethylformamide. The flask was placed in an oil bath, preheated to 150° C. and the reaction was heated for 4 hours. The hot solution was quenched in an equal volume of 1 N HCl, causing a white solid to precipitate. The cooled solution was filtered and the solid recrystallized from ethyl acetate and dried for 5 hours, m.p. 192°-194° C.
