The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 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 (2.3 mg, 20 muetaiotaomicron) was combined with HATU (7.7 mg, 20 muiotaetaomicron) in DMF (2 mL) and stirred at room temperature for 15 minutes. (1383) Compound 3 (7.7 mg, 18 muiotaetaomicron) and DIPEA (9.6 mu, 55 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 dissolved in EtOH (2 mL). A solution of IN LiOH (183 mu^, 183 muiotaetaomicron) in water was added, and the resulting solution was stirred at room temperature for 30 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 a (3 mg) as a TFA salt. MS m/z [M+H]+ calc’d for C23H25CIFN5O4, 490.16; found 488.
