Adding a certain compound to certain chemical reactions, such as: 2458-26-6, name is 3-Phenyl-1H-pyrazole, 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 2458-26-6, Safety of 3-Phenyl-1H-pyrazole
Examples 42-48Preparation of N-(2,6-difluorophenyl)[5-(1-methyl-3-phenylpyrazol-5-yl](2-thienyl)}carboxamide (93) To a solution of 90 (1 g, 6.9 mmol) in THF (50 mL) was added NaH (0.66 g, 27.6 mmol). The mixture was stirred for 1 h and the MeI (1.97 g, 13.8 mmol) was added in one potion. The reaction mixture was stirred for 18 h at room temperature. The reaction was quenched with MeOH and solvent was removed in vacuo. The residue was treated with water and EtOAc. The organic layer was separated and aqueous was extracted with EtOAc. The combined organic phase was dried over Na2SO4, filtered, concentrated to give crude product. The crude product was purified on ISCO columns. Fractions containing pure product were combined and evaporated. The yellow oil 91 (0.53 g, 48%) was obtained.
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-Phenyl-1H-pyrazole, other downstream synthetic routes, hurry up and to see.
