Application of 16681-70-2, New Advances in Chemical Research in 2021.In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid, molecular formula is C3H3N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
lH-l,2,3-triazole-4-carboxylic acid (3.8 mg, 34 muiotaetaomicron) was combined with HATU (12.9 mg, 34 muiotaetaomicron) in DMF (2 mL) and stirred at room temperature for 15 minutes. (1374) Compound 3 (60 mg, 137 muiotaetaomicron) and DIPEA (16 mu^, 92 muiotaetaomicron) were then added. The solution was stirred at room temperature for 15 minutes, at which time LCMS showed reaction completion. The solvent was removed in vacuo and the crude residue was purified by reverse phase chromatography to yield Compound b (18.5 mg) as a TFA salt. MS m/z [M+H]+ calc’d for C26H31CIF 5O4, 532.21 ; found 532.
I am very proud of our efforts over the past few months and hope to 1H-[1,2,3]Triazole-4-carboxylic acid help many people in the next few years.
