The new fused imidazo[5,1‐ c ]‐1,2,4‐triazoles 4 were obtained by cyclization of the corresponding 2‐imidazolidinone 4‐phenylhydrazones 2 which were obtained by the action of phenylhydrazine on the arylmethylene derivatives of 4‐thioxo‐2‐imidazolidinone 1 . The benzylimino derivatives 6 were obtained by the reaction of benzylamine with 1 . Alkylation of 1 with phenacyl bromide and/or ethyl bromoacetate afforded the S ‐alkyl derivatives 7.
