Participants

Reaction Steps

A 0.46 g. amount of sodium metal is dissolved in 150 ml. of absolute ethanol, then 16.5 g. of 2-hydrazinobenzothiazole is added, followed by 12.9 g. of cinnamonitrile. The reaction mixture is refluxed for 16 hours, then is cooled. Some of the solvent is removed in vacuo and the mixture is filtered. The precipitate is washed with hexane to give 25.67 g. of crude product. A 3.0 g. amount of this material is recrystallized from acetone-hexane to give 2.35 g. of the product of the Example as buff colored prisms, m.p. 270°-271.5° C.
