Research speed reading in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic. 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. 4928-87-4
To a reaction of H-, 2, 4-triazole-3 -carboxylic acid (226 mg, 2.0 mmol) and 3- methoxybenzylamine (0.28 mL, 2.2 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, concentrated under reduced pressure and chromatographed on silica gel using MeOH and DCM (2:98) as eluents to get the desired amide 7 (170.9 mg, 37 % yield) as a white solid compound. -NMR (400 MHz, DMSO-de): <514.76-14.65 (m, 1H), 9.15 (br s, 1H), 8.48 (br s, 1H), 7.23 (t, J= 8 Hz, 1H), 6.90-6.88 (m, 2H), 6.82-6.80 (m, 1H), 4.43 (d, J= 6 Hz, 2H), 3.73 (s, 3H) ppm. MH+ = 233.2 m/z.
In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model. Read on for other articles about 4928-87-4.
