The ring‐closure of the 5‐amino‐1‐(2‐aminophenyl)‐3‐methylthio‐1 H ‐1,2,4‐triazole derivatives 3 and 4 with different simple and cyclic C 1 components lead to the formation of 1,2,4‐triazolo[1,5‐α]‐1,3,5‐benzotriazepines 5–6 , their 4,5‐dihydro‐ 7 , different 5‐spiro‐homocyclic‐ 8–13 , and 5‐spiro‐heterocyclic‐ 14‐15 analogues. The structure of the compounds obtained was proved with the use of their ir, uv, 1 H‐nmr and 13 C‐nmr spectra.
