Some common heterocyclic compound, 135242-93-2, name is (1-Methyl-1H-[1,2,4]triazol-3-yl)methanol, molecular formula is C4H7N3O, 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. SDS of cas: 135242-93-2
f 6-(1-Methyl-1H-1,2,4-triazol-3-ylmethoxy)-7-phenyl-3-(pyrazin-2-yl)-1,2,4-triazolo[4,3-b]pyridazine To a solution of (1-methyl-1H-1,2,4-triazol-3-yl)methanol (prepared using the conditions described in EP-A-421210; 0.044 g, 0.39 mmol) in dimethyl formamide (10 ml) was added sodium hydride (0.016 g of a 60% dispersion in oil, 0.390 mmol) and the reaction mixture was stirred at room temperature under nitrogen for 0.5 h. After this time, the product from Example 1 step e) (0.1 g, 0.325 mmol) was added and the reaction mixture stirred for 2.5 h. The solvent was removed under high vacuum. Water (5 ml) was added to the residue and the solid produced was collected by filtration. The solid was recrystallized from ethyl acetate/ethanol to give the required product (0.049 g, m.p. 256.9-257.8 C.). 1H NMR (360 MHz, CDCl3) delta 3.94 (3H, s), 5.62 (2H, s), 7.47 (3H, m), 7.67 (2H, m), 8.04 (1H, s), 8.10 (1H, s), 870 (1H, s), 8.84 (1H, s), 9.80 (1H, s) MS (ES+) m/e 386 [MH+].
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 135242-93-2, its application will become more common.
