Electric Literature of 956317-36-5, 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, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
HATU (0.090 g, 0.24 mmol) was added to a solution of 2-[3-(5-fluoropyridin-2-yl)-1,2-oxazol-5-yl]ethanamine (0.053 g, 0.16mmol), 5-methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid (0.038 g,0.19 mmol) and DIPEA (0.082 mL, 0.47 mmol) in DMF (5 mL),followed by stirring at room temperature for 16 h. An aqueousNaHCO3 solution was added to the reaction solution, followedby extraction with EtOAc. The organic layer was washed with brine and was dried over MgSO4. The desiccant was then removedby filtration, and the solvent was distilled off under reduced pressure.The resulting residue was purified by column chromatography(20-80% EtOAc in hexanes) to give the title compound 20 asa colorless powder (0.060 g, 97%).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
