Reference of 135242-93-2, New Advances in Chemical Research in 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 135242-93-2, name is (1-Methyl-1H-[1,2,4]triazol-3-yl)methanol, molecular formula is C4H7N3O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
b N,N-Diethyl-N-[6-(1-methyl-1 H-1,2,4-triazol-3-ylmethoxy)-3-phenyl-1,2,4-triazolo[4,3-b]pyridazin-7-yl]amine To a solution of N-(6-chloro-3-phenyl-1,2,4-triazolo[4,3-b]pyridazin-7-yl)-N,N-diethylamine (180 mg, 0.33 mmol) and (1-methyl-1 H-1,2,4-triazol-3-yl)methanol (68 mg) in dry DMF (5 ml) was added sodium hydride (60% dispersion in oil, 34 mg, 0.36 mmol). The mixture was stirred at room temperature for 3 hours. The reaction mixture was diluted with water (50 ml) and extracted with dichloromethane (3*25 ml). The combined extracts were washed with brine, dried over magnesium sulphate, filtered and evaporated. The solid was recrystallized from ethyl acetate, and collected by filtration to afford the title pyridazine (81 mg, 36%). 1H NMR (500 MHz, DMSO-d6) delta1.08 (6 H, t, J=8.5 Hz), 3.31 (4 H, q, J=8.5 Hz), 3.87 (3 H, s), 5.50 (2 H, s), 7.22 (1 H, s), 7.47-7.59 (3 H, m), 8.37 (2 H, d, J=8.5 Hz), 8.51 (1 H, s). MS (ES+) 379 [MH]+.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about (1-Methyl-1H-[1,2,4]triazol-3-yl)methanol, hurry up and to see.
