実験手順
40 g of the pyridine-2,6-dicarboxylic acid N-oxide was dissolved in 100 ml of methanol. 5 ml of sulfuric acid was added to the solution. The admixture was then heated under reflux for 2 hours and allowed, to cool so that crystals were deposited. The crystals thus deposited were filtered to obtain 28 g of 6-methoxycarbonylpyridine-2-carboxylic acid.
