Electric Literature of 16681-70-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 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.
[0819] 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) stirred at room temperature for 10 minutes; DIPEA(1 eq.) was added and the mixture was stirred for 1 minute.Compound 2 (10 mg, 30 f.tmol) was dissolved in DMF (0.5mL) and DIPEA (5.2 f.LL, 30 f.tmol) was added, followed byaddition 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 (5.2 mg) as a TFA salt. MS m/z [M+Htcalc’d for C27H31ClFN50 4 , 544.21. found 544. Half of thecrude product was used in the next step without purification.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1H-[1,2,3]Triazole-4-carboxylic acid, other downstream synthetic routes, hurry up and to see.
