Synthetic Route of 956317-36-5, New Advances in Chemical Research 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, molecular formula is C10H9N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
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).
