Synthetic Route of 1001401-62-2, New Advances in Chemical Research in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 1001401-62-2, name is 2-(2H-1,2,3-Triazol-2-yl)benzoic acid, molecular formula is C9H7N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
A solution of2-(2H-1,2,3-triazol-2-yl)benzoic acid (P. Coleman, J. Schreier,W02007/126934) (1 g, 4.1 mmol) in SOCb (10 mL) was stirred at 80 C for 30 min. Thesolvent was removed under reduced pressure and toluene (10 mL) was added to give solution A.The product from step 4 (1 g, 4.1 mmol) was dissolved in DCM (10 mL), DIEA (1.58 g, 1225 mmol) added, and then solution A added at 0 C. The resulting mixture was stirred at RT for 2 h,then poured into water (10 mL) and extracted with DCM (10 mL x 3). The combined organiclayers were washed with brine (10 mL), dried overNa2S04, filtered and concentrated in vacuo.The residue was purified by chromatography on silica (petroleum ether : EtOAc = 10 : 1 to = 3 :1) then purified by prep. TLC (petroleum ether: EtOAc = 1 : 1) to give the title compound (0.230 g). LRMS m/z (M+H) 416.0, 418.0 found, 416.1, 418.1 required
