Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid, A new synthetic method of this compound is introduced below., Product Details of 16681-70-2
[0614] 1H-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 5 (9 mg, 30 fllllOI) 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 the title compound c as a TFA salt (1 mg). MS m/z[M+Hr calc’d for C25H29CIFN50 4 , 518.19. found 518.
The synthetic route of 16681-70-2 has been constantly updated, and we look forward to future research findings.
