Abstract: | 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. |
