• Claisen and Meyer^<2)> reported the pyrolysis of acetoacetamide (I) to afford 2,4-dimethyl-5-oxo-1,6-dihydro-3-pyridinecarboxamide (II-a), which, on hydrolysis, was converted to the lutidone carboxylic acid (III-a). We re-tested this reaction and found that 3-acetyl-4-amino-6-methyl-2-pyridone (II-b) is the proper structure for the pyrolyzed product and that 3-acetyl-4-hydroxy-6-methyl-2-pyridone (III-b) is the correct one for the hydrolyzed compound.
