Adding a certain compound to certain chemical reactions, such as: 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid, belongs to Triazoles compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 16681-70-2, Recommanded Product: 16681-70-2
1,2,3-Triazole-4-carboxylic acid (14 mg, 124 mumol), DIPEA (86.3 muL, 496 mumol) and HATU (47.1 mg, 124 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-(2-oxo-pyrrolidin-1-yl)-ethyl ester (52.6 mg, 124 mumol). The resulting mixture was stirred for 15 minutes and the reaction was quenched with AcOH. The product purified by preparative HPLC and lyophilized to yield the title compound (13 mg; purity 95%). MS m/z [M+H]+ calc’d for C28H33N5O5, 520.25. found 520.4.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1H-[1,2,3]Triazole-4-carboxylic acid, and friends who are interested can also refer to it.
