These common heterocyclic compound, 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Formula: C3H3N3O2
[0688] Compound 3 (7 .0 mg, 16 f.tmol) was combined withDMF (0.5 mL), 1H-1,2,3-triazole-5-carboxylic acid (2.0 mg,18 f.tmol), HATU (6.8 mg, 18 f.tmol) and DIPEA (8.5 f.LL, 49f.tmol). The mixture was stirred for 30 minutes after whichtime LCMS showed the desired product formation, Compound4, which was used directly in the next step.
The synthetic route of 1H-[1,2,3]Triazole-4-carboxylic acid has been constantly updated, and we look forward to future research findings.
