Versuchsvorschrift
According to the same manner as that of Example a-1 except that 4.90 g of 3-(2-hydroxyethoxy)benzaldehyde was used in place of 3-[(methoxycarbonyl)methoxy]benzaldehyde, and 4.86 g of 3-acetyl-4-hydroxy-1,6-dimethyl-2(1H)-pyridinone was used in place of 3-acetyl-4-hydroxy-6-methyl-2(1H)-pyridinone, 1.41 g of 4-hydroxy-3-[3-[3-(2-hydroxyethoxy)phenyl]-1-oxo-2-propenyl]-1,6-dimethyl-2(1H)-pyridinone [Compound No. (40a)] was obtained as a yellow crystal.
