Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 288-36-8, name is 1H-1,2,3-Triazole, This compound has unique chemical properties. The synthetic route is as follows., 288-36-8
1,2,3-triazole (3.45 g, 50 mmol), 2-iodo-5-methylbenzoic acid (5.24 g, 20 mmol), cesium carbonate (0.57 g, 3.6 mmol), cuprous iodide (0.38 g, 2 mmol), trans-N, N’-dimethyl-1,2-cyclohexanediamine (0.51 g, 3.6 mmol), N, N-dimethylformamide (30 mL)was added sequentially to a 100 mL single-necked round bottom flask and gradually heated under nitrogen to 100 C for 4 hours. The reaction was quenched, cooled, diluted with tap water and washed with ethyl acetate (200 mL x 2). The aqueous layer was acidified with concentrated hydrochloric acid (pH = 1~2) and extracted with ethyl acetate (200 mL x 2). The organic layers were combined and dried over anhydrous sodium sulfate. The filtrate was evaporated under reduced pressure and purified by column chromatography (dichloromethane / methanol (v/v) = 50/1) to give the title compound (yellow solid, 2.76 g, 68%).
