The chemical industry reduces the impact on the environment during synthesis 2458-26-6, name is 3-Phenyl-1H-pyrazole, I believe this compound will play a more active role in future production and life. 2458-26-6
A solution of 3-phenyl-leta-pyrazole (2.98 g, 20.67 mmol) in anhydrous N,N- dimethylformamide (40 ml) was treated with N-bromosuccinimide (3.68 g, 20.67 mmol) in one portion and then stirred at room temperature for 1 h. The reaction was evaporated under reduced pressure and the resulting residue was dissolved in ethanol (15 ml) and diluted with water (100 ml) to precipitate the crude product. The solids were collected by filtration and dried via air suction. The product was purified by recrystallization from acetonitrile- water to give the title compound (4.19 g, 91 %) as a white solid. MS(ES)+ m/e 224 [M+H]+.
