7411-23-6, Name is 3,5-Dibromo-1H-1,2,4-triazole, 7411-23-6, belongs to Triazoles compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows.
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).
Statistics shows that 3,5-Dibromo-1H-1,2,4-triazole is playing an increasingly important role. we look forward to future research findings about 7411-23-6.
