Reduction of 3-cyano-5-(3,4-dimethoxyphenyl)-1-methylpyrazinium ion by the hydride reagents such as sodium borohydride or Hantzsch ester gave the 1,6-dihydropyrazine derivative, and the 1,4,5,6-tetrahydropyrazine derivative on further reduction.Addition of hydroxide ion to the pyrazinium ion gave mainly a 6-hydroxy-pseudobase, accompanied by the minor formation of a 2-hydroxy-pseudobase.Photoreaction of the pseudobase mixture gave a product from the major pseudobase but thermal transformation gave another product from the minor pseudobase.
