1145-01-3<\/a>, A common compound: 1145-01-3, name is 3,5-Diphenyl-1H-pyrazole, belongs to pyrazoles-derivatives compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.<\/p>\n

Potassium hydroxide (0.800 g, 14 103 mol) was treated with 9.0 mL of DMSO and the resulting mixture was magnetically stirred at room temperature (ca. 298 K) for 30 min. After this period 3,5-diphenylpyrazole (0.788 g, 3.58 103 mol) was added and the stirring was maintained for 30 min at 298 K. Then, 1-chloro-2-methoxyethane (4.0 mL, 45 103 mol) was gradually added and the reaction mixture was left overnight under stirring at 298 K. After this period, 50 mL of iced cold water was added to eliminatethe unreacted KOH; the organic phase was then extracted with diethylether and washed repeatedly with water, dried over Na2SO4 and filtered. Then, the filtrate was concentrated to dryness on arotary evaporator. The solid formed was collected and later on dried in vacuum for 3 days. [Yield: 0.880 g, (88%)]. Characterization data:Anal (%).
