A new synthetic route of 154471-65-5

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-Methyl-3-(trifluoromethyl)-1H-pyrazole, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 154471-65-5, name is 1-Methyl-3-(trifluoromethyl)-1H-pyrazole, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 154471-65-5, Application In Synthesis of 1-Methyl-3-(trifluoromethyl)-1H-pyrazole

Into a 10-mL sealed tube purged and maintained with an inert atmosphere of argon, was placed a solution of 1-methyl-3-(trifluoromethyl)-1H-pyrazole (10.0 g, 66.62 mmol) and NBS (16.2 g, 66.62 mmol) in DMF (100 mL). The resulting solution was stirred overnight at 50 C. in an oil bath. The reaction was then quenched by the addition of ice water (1 L). The resulting solution was extracted with ether (3×200 mL), the organic layers combined and dried over anhydrous Na2SO4, filtered and then concentrated to provide the desired product as a yellow oil (12.0 g, crude), which was used as is without further purification. 1H NMR (400 MHz, CDCl3): delta 7.46 (s, 1H), 3.94 (s, 3H) ppm.
