Versuchsvorschrift

A mixture of 5.97 gm (0.0366 mole) of n-butyl 4-pyridinyl ketone, 5.45 gm (0.04 mole) of benzoic acid hydrazide and 100 ml of absolute ethanol is refluxed 4.5 hr. The hot solution is filtered. The filtrate is diluted with water to the cloud point, cooled to room temperature and chilled. The solids which deposit are collected, washed with water and dried to yield 7.89 gm (77%) of the title compound having a melting point of 142.1° C.
