In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 4923-01-7 as follows. Safety of 5-Methyl-4H-1,2,4-triazol-3-amine
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 150C 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.
According to the analysis of related databases, 4923-01-7, the application of this compound in the production field has become more and more popular.
