Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 135242-93-2, name is (1-Methyl-1H-[1,2,4]triazol-3-yl)methanol, A new synthetic method of this compound is introduced below., Application In Synthesis of (1-Methyl-1H-[1,2,4]triazol-3-yl)methanol
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 mumop. The mixture was stirred at 15-20 C. for 2 h. 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 (300 mg, 2.70 mmol, 76% yield). 1H NMR (chloroform-d 400 MHz) delta 10.01 (s, 1H), 8.19 (s, 1H), 4.06 (s, 3H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
