5-arylaminomethyl-1-benzoylamino-1,2,3-triazoles 9, which on treatment with phosphorus pentachloride gave the [1,2,3]triazolo[5,1-f][1,2,4]triazine derivatives 10. Hydrolysis of the amide bond in 9 gave the 1-aminotriazoles 11, which with ethyl orthoformate gave the [1,2,3]triazolo[5,1-f][1,2,4]triazines 12, whereas with phosgene the triazolotriazinones 13 were obtained.
