The 2-, 4-, and 6-pyridones related to 1-methyl-nicotinonitrile

The 2-, 4-, and 6-pyridones related to 1-methylnicotinonitrile have been synthesized and their properties compared. The 4-pyridone is a new compound and the 2-pyridone has not been obtained synthetically before. The 4- and 6-pyridones are identical to two of the products obtained from enzymatic oxidation of nicotinonitrile methiodide.
