Reaction Steps
10.5 Grams of diethyl 3-aminoanilino-methylenemalonate are dissolved in 80 ml of diphenyl oxide, 8 ml of acetic anhydride are added and the mixture is gradually heated to 250° C. and maintained under reflux for 10 minutes. The mixture is allowed to cool, 20 ml of ethanol are added and the solid is filtered off and washed with ethanol. The product is recrystallized in dimethylformamide and 4.6 grams of a solid are obtained, of melting point 295° to 300° C.
