Also, Fife et al., cited hereabove and Heterocycles 22:93-96(1984), reported the reaction of 3-methylpyridine-1-oxide with dimethyl-carbamoyl chloride to give 3-methyl-1-dimethylcarbamoyloxypyridinium chloride. Reaction of this pyridinium salt with potassium cyanide in water gave 3-methyl-2-cyanopyridine (89%) and the 6-isomer (11%).
