The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 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.
To a mixture of (1-methyl-1H-1,2,4-triazol-3-yl)methanol (400 mg, 3.54 mmol) and iodobenzene diacetate (1.25 g, 3.89 mmol) in dichloromethane (10 mL) was added TEMPO ((2,2,6,6-tetramethylpiperidin-1-yl)oxyl) (56 mg, 354 mumol. The mixture was stirred at 15-20 C. for 2h. The mixture was concentrated in vacuo. The residue was purified by silica gel chromatography (petroleum ether:ethyl acetate=1:2) to give 1-methyl-1H-1,2,4-triazole-3-carbaldehyde.
By the way, if you are interested in learning more fun chemistry with your kids, get your hands into one chemistry set now, and start enjoying the best part of chemistry: experiments about (1-Methyl-1H-[1,2,4]triazol-3-yl)methanol.
