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. 138624-97-2, name is 1-Benzyl-1H-1,2,4-triazole-3-carboxylic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 138624-97-2
M-10 (25 mg) was dissolved in 2 mL of dichloromethane and 1 mL of trifluoroacetic acid, and after 1 hour of reaction, the solvent was spin-dried to obtain the intermediate amine. Subsequently, the intermediate was dissolved in DMSO (1 mL), and 35 mg of acid-6 was added (the acid was purchased commercially, or the preparation of the acid please refer to: CN 105121432 A, J. Med. Chem. 2017, 60, 1247 ), HATU (56mg), DIPEA (60mg), the reaction was overnight, added water and ethyl acetate extraction, the organic layer was collected, dried over anhydrous sodium sulfate, vacuum rotary evaporation to remove the solvent, HPLC separation to obtain compound ZB-R-5.
