Electric Literature of 956317-36-5, New Advances in Chemical Research in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 956317-36-5, name is 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid, molecular formula is C10H9N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
The 5 – methyl -2 – (2 H – 1, 2, 3 – triazole -2 – yl) benzoic acid (2.03 g, 10 mmol) is added to the 100 ml round bottom flask in the single port, for anhydrous dichloromethane (20 ml) dissolved, then slowly adding thionyl chloride (15 ml, 200 mmol) and pyridine (0.15 ml, 2 mmol). The reaction solution gradually heating to reflux, the reaction 3 hours after stopping the reaction, cooling, slowly evaporating the solvent under reduced pressure, the obtained product can be directly into the next step.
We very much hope you enjoy reading the articles and that you will join us to present your own research about 956317-36-5, Happy reading!
