Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 1001401-62-2, name is 2-(2H-1,2,3-Triazol-2-yl)benzoic acid, A new synthetic method of this compound is introduced below., Safety of 2-(2H-1,2,3-Triazol-2-yl)benzoic acid
General procedure: Et3N (0.45 mL, 3.3 mmol) was added to a solution of 2-(1H-pyrazol-4-yl)ethanamine dihydrochloride (0.30 g, 1.6 mmol) in DMF (5 mL) at room temperature, followed by stirring. 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid (0.36 g, 1.8 mmol), HOBt.H2O (0.37 g, 2.4 mmol), and EDC.HCl (0.47 g, 2.4 mmol) were added to the reaction solution, followed by stirring at room temperature for 3 hours. An aqueous NaHCO3 solution was added to the reaction mixture, followed by extraction with EtOAc. The organic layer was washed with water and brine and was dried with Na2SO4. The desiccant was then removed by filtration, and the solvent was distilled off under reduced pressure. The resulting residue was purified by column chromatography (KP-NH: 28 g, CHCl3/MeOH=100/0 to 97/3) to give the titled compound (0.43 g, colorless and amorphous). MS (ESI pos.) m/z: 297 [M+H]+
The synthetic route of 1001401-62-2 has been constantly updated, and we look forward to future research findings.
