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. 27808-16-8, name is 4-Methyl-1H-1,2,3-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. 27808-16-8
N-Bromosuccinimide (5.89 g, 33.1 mmol) was added to a solution of 4-methyl-1H-1,2,3-triazole (2.50 g, 30.1 mmol) in chloroform (30 mL), and the reaction mixture was stirred for 16 hours at room temperature (15 C.). It was then diluted with dichloromethane (100 mL), washed with water (2×100 mL), dried over sodium sulfate, filtered, and concentrated in vacuo to provide the product as a white solid (4.9 g), which was used directly in the next step.
