Reaction Steps
Following the procedures outlined in Example 2, this nitrobenzene was hydrogenated to the 3,5-bis-propionamidoaniline and the latter (2.15 g., 0.0084 mol) was reacted with 1.75 g. (0.0084 mol) of 3,5-diacetyl-4,6-dihydroxy-2H-pyran-2-one to furnish 5-acetyl-4-hydroxy-3-[1-(3,5-bis-propionamidophenylamino)ethylidene]-2H-pyran-2,6(3H)-dione, m.p. 239°-241° (dec.).
