Application of 7411-23-6, 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. 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole, This compound has unique chemical properties. The synthetic route is as follows.
Triethylamine (2.0 mL, 14.5 mmol) was slowly added to a solution of 3,5-dibromo-1H-1,2,4-triazole (1.1 g, 4.83 mmol), 2-[tert- butoxycarbonyl(methyl)amino]ethyl methanesulfonate (1467 mg, 5.8 mmol) in DMF (22 mL). The reaction mixture was them stirred at 65 oC for 18 h. The reaction mixture was quenched with NH4Cl (sat. aq.) and extracted with DCM. The combined organic fractions were dried with a phase separator and reduced in vacuo. The residue was dissolved in DCM and reduced onto silica. Purification by silica column chromatography eluting with 0-5% MeOH inDCM afforded 2-(3,5-dibromo-1,2,4-triazol-1-yl)-N-methyl-ethanamine (644 mg, 2.27 mmol, 47% yield) as an orange liquid. UPLC-MS (ES+, Method A): 1.70 min, m/z 283.9 [M+H]+.
The chemical industry reduces the impact on the environment during synthesis 3,5-Dibromo-1H-1,2,4-triazole. I believe this compound will play a more active role in future production and life.
