Abstract

The regioselective oxidation of 2,3,5,6,-tetramethyl pyrazine by selenium dioxide and silver nitrate resulted in the production of, 3,6-dimethylpyrazine-2,5-dicarboxylic acid hydrate in high yields. Its crystal structure, which is reported for the very first time, consists of a unique infinite three-dimensional lattice of hydrogen-bonded acid and water molecules.
