Reaction Steps

To a boiling solution of 2.1 g. (0.01 m.) of 3,5-diacetyl-4,6-dihydroxy-2H-pyran-2-one in 150 ml. of methanol is added 2.4 g. (0.01 m.) of p-(N-benzylcarbamoyloxy)aniline and the resulting mixture is refluxed for one hour. The cooled reaction mixture is filtered and the solid is recrystallized to furnish 5-acetyl-3-[1-(p-N-benzylcarbamoyloxyphenylamino)ethylidene]-4-hydroxy-2H-pyran-2,6(3H)-dione, m.p. 195°-197° C.
