New discoveries in chemical research and development in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 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
1,2,3-Triazole-4-carboxylic acid (0.0274 g, 0.242 mmol), DIPEA (169 muL, 969 mumol) and HATU (92 mg, 242 mumol) were combined in DMF (0.2 mL) and stirred for 5 minutes at room temperature. This was then combined with (2S,4R)-4-amino-5-biphenyl-4-yl-2-hydroxymethyl-2-methyl-pentanoic acid 2-piperidin-1-yl-ethyl ester (103 mg, 242 mumol), predissolved in DMF (0.2 mL) and DIPEA (0.5 eq.). The resulting mixture was stirred for 15 minutes and the reaction was quenched with AcOH. The product was purified by preparative HPLC and lyophilized to yield the title compound (40 mg; purity 95%). MS m/z [M+H]+ calc’d for C29H37N5O4, 520.28. found 520.4.
