Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole, A new synthetic method of this compound is introduced below., Recommanded Product: 7411-23-6
Intermediate 2 -l-methyl-lH-l,2,4-triazole To 3,5-dibromo-lH-l,2,4-triazole (1.0 g, 4.41 mmol) in DMF (9 mL) was added sodium tert- pentoxide (0.485 g, 4.41 mmol). The mixture was stirred for 10 min at rt under nitrogen atmosphere, lodomethane (0.29 mL, 4.63 mmol) was added and the mixture was stirred at 40C for 2 hours. The mixture was poured onto water and extracted with diisopropylether (2x). The organic phase was washed with water (2x), brine and dried over sodium sulfate. The solvents were evaporated to give the title compound as a solid (0.83 g, 78%). MS (CI) m/z 242 [M+]. XH NMR (500 MHz, CDCI3) delta ppm 3.89 (s, 3 H).
The synthetic route of 7411-23-6 has been constantly updated, and we look forward to future research findings.
