Adding a certain compound to certain chemical reactions, such as: 1453-58-3, name is 3-Methylpyrazole, 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 1453-58-3, SDS of cas: 1453-58-3
To a 10 ml Schlek reaction tube under the protection of an inert gas such as high purity nitrogen, 0.05 mmol of a water-soluble palladium on water-bound monophosphine salt compound (5), 1.0 mmol of p-chlorobenzene, 1.3mmol of 3-methylpyrazole, 3 mmol of potassium hydroxide and 5 ml of water were added and the reaction tube was purged with nitrogen three times and then heated to 100 C with an oil bath under magnetic stirring. The reaction was refluxed for 24 hours. The oil bath was removed and the reaction was concentrated on a rotary evaporator. The residue was chromatographed on silica gel using ethyl acetate as the developing solvent to give pure product 4-methylphenyl-3-methylpyrazole in 89%
