Procedure

A solution of 4.26 gm (0.03 mole) of cyclohexanecarboxylic acid hydrazide, 3.63 gm (0.03 mole) of 4-acetylpyridine and 100 ml of ethanol is refluxed 7 hr. The solvent is evaporated in vacuo to give a white solid. The product is crystallized from ethyl acetate to yield 5.38 gm (73%) of the title compound having a melting point of 195.3° C.
