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, HPLC of Formula: C3H3N3O2
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-dimethylamino-ethyl ester (93 mg, 240 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 (30 mg; purity 95%). MS m/z [M+H]+ calc’d for C26H33N5O4, 480.25. found 480.4.
