7411-23-6, Adding some certain compound to certain chemical reactions, such as: 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 7411-23-6.
To a solution of 3,5-dibromo-1H-1,2,4-triazole (10.0 g, 44.1 mmol) in DMF (75 mL) and potassium carbonate (12.2 g, 88.2 mmol) was added iodomethane (3.02 mL, 48.5 mmol) in one portion. This gave rise to a strong exotherm from 17 C to 38 C after one minute. The reaction mixture was stirred overnight, diluted with 150 mL of EtOAc and then filtered to remove most of the inorganics. The solvent was removed under reduced pressure and the resultant yellow oily solid was partitioned between EtOAc (250 mL) and water (100 mL) and the aqueous washed with EtOAc (150 mL). The combined organics were washed with washed with brine (50 mL), dried over magnesium sulfate, filtered and the solvent removed in vacuo to give 3,5-dibromo-1-methyl-1,2,4-triazole (6.2 g, 25.8 mmol, 58% yield) as a yellow solid. UPLC-MS (ES+, Method A): 1.79 min, m/z 241.7 [M+H]+.1H NMR (400 MHz, DMSO-d6) delta 3.83 (3H).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 7411-23-6.
