Synthetic Route of 143426-52-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 143426-52-2, name is 1-(4-(Chloromethyl)phenyl)-1H-pyrazole belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
E) methyl 5- (4- ( lH-pyrazol-l-yl ) benzyl) -3-fluoro-2-hydroxy-4- methylbenzoate Tetrakis (triphenylphosphine) palladium ( 0 ) (0.40 g) was added to a mixture of methyl 3-fluoro-2-hydroxy-4-methyl-5- (4,4,5, 5-tetramethyl-l, 3, 2-dioxaborolan-2-yl ) benzoate (2.13 g) , 1- (4- (chloromethyl) phenyl) -lH-pyrazole (1.3.2 g) , sodium carbonate (1.46 g) , DME (30.0 mL) and water (10.0 mL) under argon atmosphere, and the mixture was stirred overnight at 80C. The reaction mixture was allowed to be cooled to room temperature, water was added thereto, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (0.33 g) . MS: [M+H]+ 341.1.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-(4-(Chloromethyl)phenyl)-1H-pyrazole, other downstream synthetic routes, hurry up and to see.
