The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 252742-72-6, name is 3-(Chloromethyl)-1H-1,2,4-triazol-5(4H)-one, molecular formula is C3H4ClN3O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
Example 408 5-[4-(2-(2-Fluorophenyl)acetyl]piperidino]methyl-2,4-dihydro-[1,2,4]triazol-3-one After adding 150 mg of 5-chloromethyl-2,4-dihydro-[1,2,4]triazol-3-one, 335 mg of 2-(2-fluorophenyl)-1-(piperidin-4-yl)ethanone hydrochloride and 180 mg of anhydrous potassium carbonate to acetonitrile, the mixture was stirred overnight at room temperature. Water was added to the reaction mixture and extraction was performed with ethyl acetate. The organic layer was washed with water and saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. Diethyl ether was added to the residue and the mixture was filtered to obtain the title compound (23 mg, 7percent yield). 1H-NMR (400 MHz, DMSO-d6); delta (ppm) 1.42-1.56 (2H, m), 1.79-1.87 (2H, m), 1.98-2.07 (2H, m), 2.45-2.55 (1H, m), 2.75-2.82 (2H, m), 3.25 (2H, s), 3.89 (2H, s), 7.09-7.16 (2H, m), 7.19-7.32 (2H, m), 11.20 (1H, s), 11.26 (1H, br s).
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 3-(Chloromethyl)-1H-1,2,4-triazol-5(4H)-one.
