Abstract
The cyanacetylhydrazone of ethyl benzoylpyruvate is prepared by refluxing together ethyl benzoylpyruvate and cyanacetylhydrazide. The cyanacetylhydrazones of benzoylacetone, diethyl acetonedicarboxylate, and diketohydrindene and the p-nitrophenylacetohydrazone of ethyl benzoylacetate are similarly prepared.
