A common compound: 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole, belongs to Triazoles compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound 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]+
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 7411-23-6, other downstream synthetic routes, hurry up and to see.
