These common heterocyclic compound, 4922-98-9, name is 5-Phenyl-1H-1,2,4-triazol-3-amine, its 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. Computed Properties of C8H8N4
General procedure: 3-Amino-1,2,4-triazole 8a?f (1.0 mmol), o-hydroxybenzaldehyde9a?e (1.0 mmol), acetone (10) (0.22 ml,3.0 mmol), and abs. EtOH (2 ml) were mixed in amicrowave process vial, and then 4 N solution of HCl indioxane (0.07 ml, 0.3 mmol) was added. The mixture wasirradiated at 150¡ãC for 30 min. The reaction mixture wascooled by an air flow and stirred for 24 h at roomtemperature for complete precipitation of the product. Theprecipitate was filtered off, washed with EtOH (1 ml) andEt2O (3¡Á1 ml), and dried. Compounds 1a?w were obtainedin a form of white solids.
The synthetic route of 5-Phenyl-1H-1,2,4-triazol-3-amine has been constantly updated, and we look forward to future research findings.
