Research speed reading 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. 4928-87-4, name is 1,2,4-Triazole-3-carboxylic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. HPLC of Formula: C3H3N3O2
To a reaction of H-, 2, 4-triazole-3 -carboxylic acid (226 mg, 2.0 mmol) and 4- (tert-butyl)aniline (0.33 mL, 2.1 mmol) in dry DMF (10 mL) was added 1- hydroxybenzotriazole monohydrate (337 mg, 2.2 mmol) and EDC (N-(3- Dimethylaminopropyl)-N’-ethylcarbodiimide) (422 mg, 2.2 mmol) followed by N- methylmorpholine (0.88 mL, 8.0 mmol via syringe). The mixture was stirred at room temperature under nitrogen and the solids were gradually dissolved. The contents were stirred at room temperature for 24.0 h, and then slowly diluted into iced water and extracted with DCM (2 x 50 mL). The DCM phase was washed with ice cold water (2 x 100 mL). The DCM phase was dried over anhydrous Na2S04, filtered and concentrated under reduced pressure and chromatographed on silica gel using EtOAc and Hexanes (60:40) as eluents to get the desired amide 13 (123 mg, 25 % yield) as a white solid compound. -NMR (400 MHz, DMSO-de): (br s, 1H), 7.74 (d, J= 8.8 Hz, 2H), 7.37 (d, J= 8.4 Hz, 2H), 1.28 (s, 9H) ppm. MH+ = 245.2 m/z.
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 4928-87-4
