Electric Literature of 956317-36-5, New discoveries in chemical research and development in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 956317-36-5, name is 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid, 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%).
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid.
