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. 956317-36-5, name is 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. COA of Formula: C10H9N3O2
General procedure: A mixture of the primary amine, 5-methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid 31 (0.33 g, 1.6 mmol), N,N-diisopropylethylamine(DIPEA, 2.5 mL, 14.7 mmol), and 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium 3-oxide hexafluorophosphate(HATU, 0.91 g, 2.4 mmol) in DMF (3.2 mL) was stirredat room temperature for 17 h. The reaction was quenched by theaddition of water, and the mixture was extracted with EtOAc.The organic layer was washed with brine, dried over Na2SO4, filtered,and concentrated under reduced pressure. The resulting residuewas purified by preparative HPLC to obtain the title compound7a as a colorless solid (0.18 g, 28% over 2 steps).
