실험 절차

2-Methyl-6-phenyl-4H-pyran-4-one (3.7 g) and 4-carboxybenzaldehyde (3.0 g) were added to a stirred solution of sodium ethoxide prepared by dissolving sodium (1.0 g) in ethanol (75 ml) and the mixture was heated under reflux for an hour, cooled and acidified with 2 M hydrochloric acid (25 ml). The resulting solid was recrystallised from acetic acid and then from dimethylformamide-water to give the pale yellow title product (mp >300° C.).
