In order to examine the reaction of 3-substituted 1-methoxypyridinium salts and potassium cyanide, reaction of 1-methoxy-3-cyano-, 1, 3-dimethoxy-, and 1-methoxy-3, 5-dibromopyridinium methylsulfates with potassium cyanide was carried out in water or ethanol-water mixture. The respective reaction products thereby obtained were 2, 3-dicyanopyridine in 27.8% yield, 2, 5-dicyanopyridine in 17.6% yield, 2-cyano-3-methoxypyridine in 67.8% yield, and 2-cyano-3, 5-dibromopyridine in 70% yield.
