Procedure

A mixture of 20.0 grams (0.194 mole) of 3-cyanopyridine and 142.5 grams (0.288 mole) of monoperoxyphthalic acid, magnesium salt, hexahydrate (80% pure) in 300 mL of methylene chloride is stirred at ambient temperature for about 24 hours. After this time, the mixture is filtered, and the filtrate is concentrated under reduced pressure, yielding 3-cyanopyridine N-oxide.
