Nitric Acid → 3-Methoxy-2-methyl-6-nitropyridine

Participants

Reaction Steps

To an ice-cold mixture of 3 ml. of concentrated sulfuric acid and 3 ml. of fuming nitric acid, was added 0.5 g. of 3-methoxy-2-methylpyridine over 5 minutes. After warming spontaneously to room temperature the mixture was heated at 55°-60° C. for 6 hours. The mixture was cooled and added to 35 ml. of ice-water. After stirring 2 hours, the precipitate was collected and dried to give 3-methoxy-2-methyl-6-nitropyridine, m.p. 99°-100.5° C.
