Chlorotropic rearrangement of 3,5-dichloro-3-cyano-4-methylpyridine-2,6-(1H)-dione in the medium of polar solvents. Synthesis of 5-chloro-3-cyano-6-hydroxy-4-methylpyridin-2-one

Abstract

Isomeric conversion of 3,5-dichloro-3-cyano-4-methylpyridine-2,6(1H)-dione to 5,5-dichloro-3-cyano-4-methylpyridine-2,6(1H)-dione in polar solvents was shown. A new method for the synthesis of 5-chloro-3-cyano-6-hydroxy-4-methylpyridin-2-one was proposed.
