In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 23579-79-5, name is 3,5-Dibromo-1-methyl-1H-1,2,4-triazole belongs to Triazoles compound, it is a common compound, a new synthetic route is introduced below. Quality Control of 3,5-Dibromo-1-methyl-1H-1,2,4-triazole
Intermediate 7 3-Bromo-l-methyl-5-(3-phenylazetidi ole 3,5-Dibromo-l-methyl-lH-l,2,4-triazole (128 mg, 0.53 mmol) and 3-phenylazetidine (127 mg, 0.96 mmol) were mixed in dioxane (2 mL). N,N-Diisopropylethylamine (0.232 mL, 1.33 mmol) was added. The mixture was stirred at 120C overnight. The solvents were removed and the residue was purified by silica column chromatography using a gradient of methanol in DCM giving the title compound as a liquid (58 mg, 37%). MS (ESI+) m/z 293 [M+H]+. XH NMR (500 MHz, CDCI3) delta ppm 3.64 (s, 3 H) 3.96 – 4.04 (m, 1 H) 4.22 (t, 2 H) 4.55 (t, 2 H) 7.28 – 7.33 (m, 1 H) 7.35 – 7.42 (m, 4 H).
The synthetic route of 23579-79-5 has been constantly updated, and we look forward to future research findings.
