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. 2458-26-6, name is 3-Phenyl-1H-pyrazole belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. Safety of 3-Phenyl-1H-pyrazole
General procedure: A solution was prepared from the amine (0.781 mmol) in DCM (5.5 mL) and the boronic acid(1.25 mmol) and NEt3 (0.039 g, 54 muL, 0.391 mmol) were added. A second solution was prepared with Cu(OAc)2*H2O (0.195 mmol, 0.25 equiv), NEt3 (0.039 g, 54 muL, 0.391 mmol) and pyridine (0.062 g, 63 muL, 0.781 mmol) in DCM (5.5 mL). The two solutions were introduced to independent 5 mL sample loop as shown in (Scheme 1). The dispensing HPLC pumps were each set at 0.125 mL/min to achieve a residence time of 2 h. Two reverse ?tubein-tube? reactors were used in series to achieve a combined reactor volume of 30 mL which were heated at 40 C. The reaction mixture was then passed through an Omnifit column (r =0.33 cm, h = 10.00 cm) filled with QP-DMA followed by a back pressure regulator (175 psi).The crude reaction mixture was passed through a plug of silica to remove base line residue and the solvent evaporated under reduced pressure. The resultant crude material was then purified using flash chromatography.
The synthetic route of 2458-26-6 has been constantly updated, and we look forward to future research findings.
