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. 288-88-0, name is 1H-1,2,4-Triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. category: Triazoles
To a stirred solution of 4-fluro benzaldehyde (1.0 g, 0.8 mmol) in dry DMF (5 mL), 1 H-1 ,2,4-triazole (660 mg, 0.9 mmol) and K2CO3 (2.2 g, 1.6 mmol) were added at RT and the resulting mixture was stirred overnight at 1 10 C. After completion of reaction, ice water (2 mL) was added and the mixture was extracted with EtOAc (2 x 20 ml_). The combined organic layer was washed with brine (2 ml_), dried over Na2S04 and concentrated under vacuum. The resulting product was used in next step without further purification. Yield: 46% (610 mg, white solid). LCMS: (Method A) 174.1 (M+H), Rt.1.27 min, 67.51 % (Max).
