Reference of 2458-26-6, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 2458-26-6, name is 3-Phenyl-1H-pyrazole, This compound has unique chemical properties. The synthetic route is as follows.
Step 3: 1-Delta4′-[3-Methyl-4-(3-phenyl-pyrazol-1-ylmethyl)-isoxazol-5-yl]-biphenyl-4-yl}-cyclopropanecarboxylic acid 1-[4′-(4-Bromomethyl-3-methyl-isoxazol-5-yl)-biphenyl-4-yl]-cyclopropanecarboxylic acid ethyl ester (0.132 g, 0.3 mmol) and 3-phenyl-1H-pyrazole (0.043 g, 0.3 mmol) were combined in DMF. Sodium hydride (60% in mineral oil; 0.014 g, 0.35 mmol) was added, and the reaction was stirred at room temperature for 1.5 hours. Once no starting material was seen by analytical LCMS, the mixture was diluted with EtOAc and 1N aqueous HCl. The aqueous layer was extracted with EtOAc, and the combined organic layers were washed with H2O and brine, and then dried over Na2SO4, filtered, and concentrated. The residue was purified by preparative HPLC to give the title compound.
The chemical industry reduces the impact on the environment during synthesis 3-Phenyl-1H-pyrazole. I believe this compound will play a more active role in future production and life.
