Adding a certain compound to certain chemical reactions, such as: 4928-87-4, name is 1,2,4-Triazole-3-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 4928-87-4, COA 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.
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, 1,2,4-Triazole-3-carboxylic acid, other downstream synthetic routes, hurry up and to see.
