A common compound: 288-36-8, name is 1H-1,2,3-Triazole, belongs to Triazoles compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 288-36-8
To a round-bottomed flask equipped with an overhead magnetic stirrer, reflux condenser, and nitrogen inlet were added 2-Fluoro-6-iodobenzoic acid (2.5 g, 9.4 mmol), Cul (0.09 g, 0.47 mmol), and CS2CO3 (6.1 g, 18.8 mmol). To these solids were added dioxane (12.5 ml_), water (0.05 ml_), 1 H-1 ,2,3-triazole (1.09 ml_, 18.8 mmol), and finally (1 R,2R)-N1 ,N2-dimethylcyclohexane-1 ,2-diamine (0.3 ml_, 1.88 mmol). The mixture was then warmed to 100 C ON. The day after the mixture was cooled and MTBE and water were added. After vigorous mixing, the layers were separated and the bottom aqueous layer was acidified to pH 2 with 6N HCI. The aqueous phase was then extracted with DCM (3x). The combined organic layers were dried, and concentrated The residue was purified by FC on S1O2 column (eluent : from DCM to DCM:MeOH 90:10) to afford 2-fluoro-6-(2H-1 ,2,3-triazol-2-yl)benzoic acid (p186, 1.1 g, y= 56%). MS (m/z): 208.0 [M+H]+
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 288-36-8, other downstream synthetic routes, hurry up and to see.
