Procedure
A mixture of 12.11 gm (0.1 mole) of 4-acetylpyridine, 18.85 gm (0.1 mole) of phenyl carbazate hydrochloride and 250 ml of absolute ethanol is refluxed 6 hr and cooled. The reaction mixture is evaporated to dryness in vacuo to give a rose-colored solid. The crude product is crystallized from absolute ethanol to yield 28.13 gm (97%) of the title compound having a melting point of 159.1° C.
