Reaction Steps

To 24.11 gm (0.1 mole) of benzhydryl carbazate in 200 ml of warm absolute ethanol is added 10.66 gm (0.1 mole) of 4-pyridinecarboxaldehyde in 75 ml of absolute ethanol. The mixture is refluxed 7 hr and cooled. The solvent is removed in vacuo. Recrystallization from ethanol/Skellysolve B yields 26.03 gm (78.5%) of the title compound having a melting point of 159°-160° C.
