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.
To a solution of 50 (1.08 g, 4.03 mmol) in DMF (20 mL) was added3-methyl-1H-1,2,4-triazole (0.469 g, 5.65 mmol) and K2CO3(0.781 g, 5.65 mmol) at r.t. The mixture was stirred at r.t.overnight and warmed to 60C for 2 h. After cooling to r.t.,water was added to the mixture. The solid was collected byfiltration, washed with water, and dried to give 51b (0.870 g,2.77 mmol, 69%) as a tan solid. 1H-NMR (300 MHz, DMSOd6) delta: 1.56 (9H, s), 2.43 (3H, s), 2.54 (3H, d, J=1.1 Hz), 8.56(1H, s), 9.10 (1H, s), 9.43 (1H, d, J=1.1 Hz). MS (ESI/APCI)m/z 315.2 [M+H]+.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 7170-01-6.
