New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. 7411-23-6
1-(2-chloroethyl)piperidine hydrochloride (243 mg, 1.32 mmol), 3,5-dibromo-1H-1,2,4-triazole (250 mg, 1.1 mmol) and potassium carbonate (640 mg, 4.6 mmol) were added to DMF (5 mL) in a 25 mL round bottom flask. The reaction was then stirred for 18 h at 50 C under nitrogen. The solvent was removed in vacuo, water was added, and the product extracted with DCM (3 times). The organic phase was dried over a phase separator and the solvent removed in vacuo. The product was purified by silica column chromatography eluting with 0-10% MeOH in DCM to give [1-[2-(3,5-dibromo-1,2,4-triazol-1-yl)ethyl]piperidine (224 mg, 0.66 mmol, 60% yield)] as a yellow oil. UPLC-MS (ES+, Method A), 0.87 min, m/z 339.0 [M+H]+
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 3,5-Dibromo-1H-1,2,4-triazole ,and how the biochemistry of the body works.
