Procedure

To a boiling solution of 4.24 g. (0.02 m.) of 3,5-diacetyl-4,6-dihydroxy-2H-pyran-2-one in 200 ml. of methanol is added 2.18 g. (0.02 m.) of o-hydroxyaniline. The resulting mixture is refluxed overnight and filtered to yield 5-acetyl-4-hydroxy-3-[1-(o-hydroxyphenylamino)ethylidene]-2H-pyran-2,6(3H)-dione, m.p. 210° -212° C.
