The 4-nitro substituted starting material is prepared by contacting 2,6-dimethylpyridine N-oxide with nitric acid and sulfuric acid thereby forming the 2,6-dimethyl-4-nitropyridine. The N-oxide is reduced to the pyridine compound with phosphorous trichloride and then oxidized to the 4-nitropyridine 2,6-dicarboxylic acid with potassium permanganate.
