A solution of 4.05 gm (0.03 mole) of 4-propionylpyridine, 3.96 gm (0.03 mole) of t-butylcarbazate and 100 ml of absolute ethanol is refluxed 6 hr. The reaction mixture is treated with decolorizing carbon and filtered. The filtrate yields crystals on cooling. The product is collected, washed with Skellysolve B and dried to yield 3.16 gm (40%) of the title compound having a melting point of 170.1° C.
