5-Diazoimidazole-4-carboxamide couples with reactive methylenic substrates to afford a series of imidazolylhydrazones which cyclise in acid or alkali to imidazotriazines.Hydrazones with cyano-substituents cyclise in acid to yield 7-aminoimidazotriazines whereas hydrazones with acetyl groups undergo acidic dehydration to form bicycles with a 7-methylene substituent.In basic conditions, hydrazones with a reactive ester group cyclise to imidazotriazin-7(4H)-ones with loss of an alcohol moiety.Ethyl 7-amino-3-carbamoylimidazotriazine-6-carboxylate hydrolyses in boiling 2N-hydrochloric acid, forms an N-acetyl derivative, and reacts with secondary heteroalicyclic amines to form amides.
