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. 118863-62-0, name is 3-(4-Bromophenyl)-1H-[1,2,4]triazole, This compound has unique chemical properties. The synthetic route is as follows., name: 3-(4-Bromophenyl)-1H-[1,2,4]triazole
Example 8 Preparation of 3-(4-bromophenyl)-1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazole (C5) (0174) (0175) 3-(4-Bromophenyl)-1H-1,2,4-triazole (C4) (10.9 g, 48.5 mmol), copper(I) iodide (2.38 g, 12.5 mmol), and cesium carbonate (30.3 g, 93.0 mmol) in a round-bottomed flask was flushed with nitrogen. Dimethylsulfoxide (85 mL) was added, followed by 1-iodo-4-(trifluoromethoxy)benzene (13.2 g, 45.8 mmol). The reaction was degassed for 5 minutes, then heated at 100 C. for 3 days. The reaction was cooled to room temperature, diluted with ethyl acetate, and filtered through a plug of Celite rinsing with ethyl acetate. To the filtrate was added saturated ammonium chloride and stirred for 1.5 hours. The layers were separated and the aqueous layer was extracted with ethyl acetate (3¡Á). The combined organic layers were dried over magnesium sulfate, filtered, and concentrated onto Celite. Purification by flash column chromatography using 0-40% EtOAc/hexanes as eluent provided the title compound as an off-white solid (9.65 g, 52%): mp 109-112 C.; 1H NMR (400 MHz, CDCl3) delta 8.56 (s, 1H), 8.10-8.03 (m, 2H), 7.83-7.75 (m, 2H), 7.64-7.57 (m, 2H), 7.42-7.35 (m, 2H); ESIMS m/z 386 ([M+21-1 ]+).
According to the analysis of related databases, 118863-62-0, the application of this compound in the production field has become more and more popular.
