실험 절차

A mixture of methyl 1-(3-pyridylmethyl)-2,4-dioxopiperidine-3-carboxylate (8.50 g), acetonitrile (100 ml) and water (1.4 ml) is refluxed for one hour. The mixture is distilled to remove the solvent to give 1-(3-pyridylmethyl)-2,4-dioxopiperidine (6.66 g, quantitative) as crystals, m.p. 55°-60° C.
