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. 4922-98-9, name is 5-Phenyl-1H-1,2,4-triazol-3-amine belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Application In Synthesis of 5-Phenyl-1H-1,2,4-triazol-3-amine
Example 38; STEP A; To the solution of 3-phenyl-1H-1 ,2,4-triazol-5-amine (32 mg, 0.2 mmol) in DMA (0.5 ml_) was added ethyl 4-chloro-4,4-difluoro-3-oxobutanoate (40 mg, 0.2 mmol). The reaction mixture was stirred in microwave at 180 0C for 20 minutes, and then cooled to room temperature. The product, compound 38-1 , was purified by reverse phase HPLC.
