Procedure
2-Methyl-6-phenyl-4H-pyran-4-one (3.7 g) was dissolved in sodium ethoxide solution prepared by dissolving sodium (0.46 g) in ethanol (50 ml). A solution of 4-chlorobenzaldehyde (5.6 g) in ethanol (50 ml) was added and the mixture was stirred at room temperature for 24 hours. The solid which formed was recrystallised from ethanol to give the title product (mp 169°-171° C.).
