103962-05-6, name is 1-Iodo-4-(trifluoromethoxy)benzene, belongs to iodides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. category: iodides-buliding-blocks
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¡ã 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 0-40percent EtOAc/hexanes as eluent provided the title compound as an off-white solid (9.65 g, 52percent): mp 109-112¡ã 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 ]+).
The synthetic route of 103962-05-6 has been constantly updated, and we look forward to future research findings.
