New discoveries in chemical research and development in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 584-13-4, name is 4H-1,2,4-Triazol-4-amine belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Application In Synthesis of 4H-1,2,4-Triazol-4-amine
In a 500 ml three-necked flask, 8.40 g (0.1 mol) of 4-amino-1,2,4-triazole and 200 ml of acetonitrile solvent were successively added.After the solid matter was completely dissolved, 84.4 g (0.1 mol) of iodomethane was added dropwise to the solution in portions while stirring.After the addition was complete, the solution was slowly warmed to 40 C and reacted for 8 h.After purification treatment, an intermediate 1-methyl-4-amino-1,2,4-triazole iodide salt is obtained, which is then reacted with a solution containing 17 g (0.1 mol) of silver nitrate in methanol (200 ml) and distilled under reduced pressure to obtain Liquid state1-methyl-4-amino-1,2,4-triazole nitrate 14.6 g,The yield is 90.7%.
