Reaction Steps
A solution of 1.5 g. (0.01 m.) of p-ureidoaniline in 50 ml. of methanol is added to a solution of 2.1 g. (0.01 m.) of 3,5-diacetyl-4,6-dihydroxy 2H-pyran-2-one in 150 ml. of methanol. A solid is formed immediately and the mixture is refluxed for 12 hours. The filtered solid is recrystallized to give 5-acetyl-4-hydroxy-3-[1-(p-ureidophenylamino)ethylidene]-2H-pyran-2,6(3H)-dione, m.p. 250°-253° C.
