Reaction Steps
This phenol (0.86 g., 0.0045 mol) is refluxed with 3,5-diacetyl-4,6-dihydroxy-2H-pyran-2-one (0.96 g.) in 50 ml. of methanol for 10 hours. The reaction mixture is filtered and the solid is recrystallized from ethanol to furnish 5-acetyl-4-hydroxy-3-[1-(3-isobutyramido-4-hydroxyphenylamino)ethylidene]-2H-pyran-2,6(3H)-dione, m.p. 208°-209° C. (dec.).
