실험 절차

A solution of 14.26 gm (0.0956 mole) of n-butyl 4-pyridyl ketone, 5.70 gm (0.0956 mole) of formylhydrazine, 50 ml of THF, 30 ml of absolute ethanol and 0.1 gm of p-toluenesulfonic acid is refluxed 24 hr. The reaction is chilled to give a white solid which is collected and discarded. The filtrate is concentrated in vacuo to furnish a solid. This material is dissolved in methylene chloride. The methylene chloride solution is washed with saturated sodium bicarbonate solution; then brine. The organic layer is dried over magnesium sulfate and concentrated in vacuo in the presence of excess hexane to yield 5.14 gm (26%) of the title compound having a melting point of 143.4° C.
