1-Amino- and 1-benzylamino-2-methyl-3-phenacylbenzimidazolium ions undergo ring closure to give hitherto unknown 4-amino- and 4-benzylamino-2-arylpyrrolo[1,2-a]benzimidazoles when heated in an aqueous solution of sodium bicarbonate. Under the same conditions, 1-arylmethyleneamino analogs form pseudobases occurring in the open-chain tautomeric form.
