Adding a certain compound to certain chemical reactions, such as: 10010-93-2, name is 3-Methyl-5-(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 10010-93-2, Formula: C5H5F3N2
To a stirred solution of 5-methyl-3-(trifluoromethyl)-1H-pyrazole (199 mg, 1.328 mmol) in dry acetonitrile (7 mL) at room temp is added sodium hydride (63 mg of a 60% dispersion on mineral oil, 2.66 mmol). The mixture is stirred at room temp for 10 mins after which the initial effervescence had subsided to leave a colourless solution. A solution of trans-trifluoro-methanesulfonic acid 4-tert-butoxycarbonylamino-cyclohexylmethyl ester (Ex. 18 step 1) (400 mg, 1.107 mmol) in dry acetonitrile (4 mL) is then added and the mixture is stirred at room temp for 17 hours. The crude mixture is diluted with water (20 mL) and extracted with EtOAc (3×15 mL). The EtOAc extracts are combined, washed with sat. brine (30 mL), dried (MgSO4), filtered and evaporated to give a mixture of the title compounds as a pale yellow gum. This is used in the next step without further purification.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-Methyl-5-(trifluoromethyl)-1H-pyrazole, and friends who are interested can also refer to it.
