The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 74205-82-6, name is (1H-1,2,4-Triazol-1-yl)methanol, molecular formula is C3H5N3O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
PREPARATION EXAMPLE A (COMPOUND NO. 15) 2-(4-Chloro-2-fluoro-5-ethoxycarbonylmethoxyphenyl)-4, 5,6,7-tetrahydro-2H-isoindole-1,3-dione (4.0 g, made substantially by the methods described in EP 0 083 055 A2) and KOH (85%, 2.1 g) in 50 ml ethanol were stirred at room temperature for 1 hour and then evaporated to dryness. To the residue was added 100 ml chloroform and 8 ml SOCl2. The reaction mixture was then heated to reflux for 2 hours. Potassium chloride was filtered and washed with fresh chloroform. The filtrate was evaporated to dryness. To the residue was added 50 ml chloroform and 1.5 g 1-hydroxymethyl-(1H)-1,2,4-triazole. The reaction mixture was then stirred at room temperature for 5 hours. Water was added to the mixture, the organic layer was separated and washed with water and brine, dried and concentrated. The residue was purified by silica gel column chromatography to give 2.1 g of 2-(4-chloro-2-fluoro-5-[(1,2,4-triazolylmethoxy)carbonylmethoxy]phenyl)-4,5,6,7-tetrahydro-2H-isoindole-1,3-dione (Compound No. 15). M.P. 151-154 C.
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 (1H-1,2,4-Triazol-1-yl)methanol, hurry up and to see.
