New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Product Details of 16681-70-2
[0769] 3H-1,2,3-triazole-5-carboxylic acid (2.5 mg, 22f.tmol) was combined with HATU (8.4 mg, 22 flillOI) in DMF(0.3 mL) and stirred for 10 minutes; Et3N (1 eq.) was addedand the mixture was stirred for 1 minute. Compound 2 (22f.tmol) was dissolved in DMF (0.5 mL) and Et3N (3.1 f.LL, 22f.tmol) was added, followed by addition of the activated acidsolution. The mixture was stirred for 30 minutes, concentrated,and purified by preparative HPLC to yield Compounda (8 mg) as a TFA salt. MS m/z [M+Ht calc’d forC26H29CIFN50 3 , 514.19. found 514.2.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1H-[1,2,3]Triazole-4-carboxylic acid help many people in the next few years.
