Synthetic Route of 16681-70-2, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid, This compound has unique chemical properties. The synthetic route is as follows.
3H-l,2,3-triazole-4-carboxylic acid (3.4 mg, 30 muiotaetaomicron) was combined with HATU (1 1 mg, 30 muiotaetaomicron) in DMF (0.3 mL) and stirred at room temperature for 10 minutes; (1418) DIPEA (1 eq.) was added and the mixture was stirred for 1 minute. Compound 2 (10 mg, 30 muiotaetaomicron) in DMF (0.5 mL) was combined with DIPEA (5.2 muEpsilon, 30 muiotaetaomicron), then added to the activated acid solution. The resulting solution was stirred at room temperature for 30 minutes; LC/MS showed the mass of the desired product. The solvent was removed in vacuo and the crude residue was purified by reverse phase chromatography to yield Compound a (8.5 mg) as a TFA salt. MS m/z [M+H]+ calc’d for C27H31CIFN5O4, 544.21 ; found 545.2.
The chemical industry reduces the impact on the environment during synthesis 1H-[1,2,3]Triazole-4-carboxylic acid. I believe this compound will play a more active role in future production and life.
