Reference of 1455-77-2,Some common heterocyclic compound, 1455-77-2, name is 3,5-Diamino-1,2,4-triazole, molecular formula is C2H5N5, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: A suspension of 3,5-diamino-1,2,4-triazole (0.1 g, 1 mmol) in absolute EtOH (10 mL) was added to a stirring solution of azo-coupled precursors, Ia-IVa, (2 mmol) in absolute EtOH (50 mL) during a period of 10 min at 60-70 °C. The mixture was heated in water bath for 15 h at 80 °C with stirring. The mixture was filtered whilst hot and the obtained solid was washed with hot ethanol (three time) and then with diethylether. The resulted product was dried in air.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3,5-Diamino-1,2,4-triazole, its application will become more common.
