Electric Literature of 49633-25-2, 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. 49633-25-2, name is 3-Isopropylpyrazole belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
1-(4-Bromo-phenyl)-3-isopropyl-1H-pyrazole 3-Isopropylpyrazole (588 mg, 5.43 mmol), 1-bromo-4-iodobenzene (15.11 g, 53.4 mmol), cesium carbonate (5.22 g, 16.0 mmol), copper(I)iodide (1.02 g, 5.34 mmol) and N,N’-dimethylethylenediamine (570 uL, 5.34 mmol) are combined in dry N,N-dimethylformamide (100 mL) and heated at 100 C. for 3 hours under a nitrogen atmosphere. The mixture is cooled, poured into water and extracted with diethyl ether. The organic phase is dried and the solvent removed. The residue is purified by flash chromatography (30% dichloromethane in cyclohexane) to give the title compound (Yield 1.37 g) LC (METHOD 5): tR=1.47 min; Mass spectrum (ES+): m/z=265/267 [M+H]+.
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, 3-Isopropylpyrazole, other downstream synthetic routes, hurry up and to see.
