Adding a certain compound to certain chemical reactions, such as: 5334-39-4, name is 3-Methyl-4-nitro-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 5334-39-4, Product Details of 5334-39-4
To a stirred solution of 3-methyl-4-nitro-lH-pyrazole (869 mg, 0.068 mmol, 1 equiv) l-bromo-2,4-bis(trifluoromethyl)benzene (2 g, 0.068 mmoles, leq) in DMF (20 mL) was added K CO (1.89 g, 0.0136 mmol, 2 equiv) and the reaction mixture was stirred for 15 minutes. Cul (0.026 g, 0.2eq, O.OOlmoles) and L-proline (0.317 g, 0.02 mmol, 0.4 equiv.) were added to the reaction mixture. The reaction mixture was allowed to stir for 24 hour at 100 C. Product formation was confirmed by LCMS. After completion of reaction, reaction mixture was diluted with water and extracted with ethyl acetate (3×100 mL). Combined organic extracts were washed with water (4×100 mL), dried over anhydrous NaSCL and concentrated under reduced pressure to obtain which was purified by flash chromatography (EtOAc/ Hexane) to obtain titile compound l-(2,4-bis(trifluoromethyl)phenyl)-3-methyl-4- nitro-lH-pyrazole (1.0 g). LCMS 339 [M+H] +.
