New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 956317-36-5, name is 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid
5-Methyl-2- (2H-1,2,3-triazol-2-yl) benzoic acid (2.03 g, 10 mmol) was added to a 100 mL single neck round bottom flask,Dissolved with anhydrous dichloromethane (20 mL)Thionyl chloride (15 mL, 200 mmol) and pyridine (0.15 mL, 2 mmol) were then added slowly,Gradually warmed to reflux for 3 hours.The reaction was stopped, cooled and the solvent was slowly evaporated under reduced pressure. The resulting product was used directly in the next step.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid help many people in the next few years.
