実験手順
4-(4-Methoxyphenyl)butyraldehyde (5.34 g) is reacted with cyanoacetic acid (5.15 g) and sodium hydroxide (2.74 g) in a mixture of glyme (50 ml) and water (60 ml). The mixture is treated with hydrochloric acid and processed as described in Example 2A to afford the title compound (2.1 g) which on crystallization from ethyl acetate-chloroform-hexane had a melting point of 71°-73° C.
