Reaction Steps

A 0.10 g. amount of sodium metal is dissolved in 25.0 ml. of absolute ethanol, then 2.16 g. of phenylhydrazine is added, followed in 5 minutes by 3.96 g. of 3,4-dichlorocinnamonitrile. The reaction mixture is refluxed for 5 hours, then is evaporated to dryness in vacuo. The procedure, as described in Example 15, is continued with a second recrystallization from the same solvent pair and treatment with a hydrous magnesium silicate to give 1.35 g. of the desired product as colorless needles, m.p. 150°-151.5° C.
