## Abstract Some 1‐substituted 2, 3‐dimethyl‐quinoxalinium‐perchlorates were synthesized by reaction of butane‐2, 3‐dion with N‐monosubstituted 1,2‐diamino‐benzenes in strongly acidic solution. 2, 3‐dimethyl‐4‐cyclohexyl‐pyrido[2,3‐__b__]pyraziniumperchlorate was obtained from an analogous reaction
