Procedure
A mixture of 6.06 gm (0.05 mole) of 4-acetylpyridine, 5.7 gm (0.05 mole) of cyclobutanecarboxylic acid hydrazide, and 100 ml of absolute ethanol is refluxed 5 hours. The reaction mixture is evaporated in vacuo to give a solid. The product is crystallized from ethanol/ethylacetate/diethylether to give 2.92 gm (27%) of the title compound; mp 138.6°.
