Electric Literature of 16681-70-2, New Advances in Chemical Research in 2021. 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.
[0789] lH-1,2,3-triazole-5-carboxylic acid (3.4 mg, 30f.tmol) was combined with HATU (11 mg, 30 f.tmol) in DMF(0.3 mL) and stirred at room temperature for 10 minutes;DIPEA (1 eq.) was added and the mixture was stirred for 1minute. Compound 2 (1 0 mg, 30 f.tmol) was dissolved in DMF(0.5 mL) and DIPEA (5.2 f.LL, 30 fllllOI) was added, followedby addition of the activated acid solution. The mixture wasstirred at room temperature for 30 minutes, after which timeLCMS indicated desired product formation. Half of the crudeproduct was purified using reverse phase chromatography toyield Compound a (7.7 mg) as a TFA salt. MS m/z [M+Hrcalc’d for C22H28CIFN60 3 , 539.19; found 539. Half of thecrude product was carried to the next step without furtherpurification.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 1H-[1,2,3]Triazole-4-carboxylic acid.
