## Abstract The reaction of 3‐amino‐1,2,4‐triazole (**1**) with __N__‐arylmaleimides leads to azolopyrimidines **4** and **5**. The 2‐aminobenzimidazole (**2**) in the reaction with **3** gives the pyrimidobenzimidazoles **6**. In similar conditions, the reaction of amine **2** with maleic anhydrid
N NMR chemical shifts were measured for a series of substituted 5-amino-1,2,4-triazoles. The assignment of isomeric structures agrees with earlier results obtained with the use of proton-coupled I3C NMR.
