A simple strategy for the synthesis of 2-oxo-1,2-dihydropyridine-3-carbonitrile derivatives
(2-oxonicotinonitrile, 3-cyanopyridone) in good yields by substituting the halogen
atom with an oxime under mild conditions was developed. The proposed approach makes
it possible to avoid the problems associated with the hydrolysis of easily modified
groups, since the reaction is carried out in the absence of water.
