Adding a certain compound to certain chemical reactions, such as: 120068-79-3, name is 5-Amino-1-(2,6-dichloro-4-(trifluoromethyl)phenyl)-1H-pyrazole-3-carbonitrile, 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 120068-79-3, Safety of 5-Amino-1-(2,6-dichloro-4-(trifluoromethyl)phenyl)-1H-pyrazole-3-carbonitrile
General procedure: Phenylpyrazole (0.2 mmol), arylboronic acid (0.4 mmol), NIS (0.2 mmol), [Pd] (10 mol%), NaHCO3 (0.4 mmol) and C2H5OH:H2O (3:1, 10 mL), were added to a Schlenk tube. Then the tube was charged with N2 and the reaction mixture was stirred at 80 C for 18 h. After the completion of the reaction, as monitored by TLC, the mixture was cooled and filtrated. The filtrate was extracted with ethyl acetate and washed with brine. Then the combined organic extracts were dried over Na2SO4, concentrated under vacuum and the resulting residue was purified by silica gel column chromatography to afford the desired products.
