Electric Literature of 7170-01-6, These common heterocyclic compound, 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: To 3,6-dichloropyridazine (500 mg, 3.36 mmol) in 5 mL DMF are added 1H-1,2,4-triazole (460 mg, 6.71 mmol) and cesium carbonate (2.41 g, 7.38 mmol) and the reaction mixture is stirred at 60 C. for 18 h. The mixture is quenched with water and the precipitation is filtered, washed and dried to give 0.7 g of the product. (0171) C8H6N8 (M=214.19 g/mol) (0172) ESI-MS: 215 [M+H]+ (0173) 1H NMR (400 MHz, DMSO-d6) delta=9.66 (s, 1H), 8.47 (s, 1H), 8.44 (s, 1H)
Statistics shows that 3-Methyl-1H-1,2,4-triazole is playing an increasingly important role. we look forward to future research findings about 7170-01-6.
