New discoveries in chemical research and development in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 1001401-62-2, name is 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. name: 2-(2H-1,2,3-Triazol-2-yl)benzoic acid
A solution of (3R, 6i?)-6-methylpiperidin-3-ol (5.31 g, 46.1 mmol), 2-(2H-l,2,3- triazol-2-yl)benzoic acid (10.5 g, 55.3 mmol), EDC (17.7 g, 92.0 mmol), l-hydroxy-7- azabenzotriazole (12.6 g, 92.0 mmol), and triethylamine (19.3 mL, 138 mmol) in DMF (300 mL) was stirred at 50 C overnight, then diluted with saturated aqueous sodium bicarbonate and extracted 3x with ethyl acetate. The organics were washed with brine, dried over magnesium sulfate, filtered, and concentrated. The crude material was purified by silica gel gradient chromatography (0-100% ethyl acetate in hexanes), providing the titled compound as a pale yellow solid. LRMS m z (Mu+Eta) 287.3 found, 287.1 required.
