After being stirred at the same temperature for 1 h, benzoyl chloride (6a) (0.260 mL, 2.20 mmol, 1.10equiv.) was added to the mixture. After being warmed to room temperature and stirred at the same temperature for 18 h, the reaction mixture was quenched with saturated NH4Cl aq. The aqueous layer was extracted with ethyl acetate. The combined extract was washed with brine,dried over Na2SO4 and concentrated in vacuo. The residue was purified by column chromatography on silica gel with hexane : EtOAc = 5 : 1 to give phenyl(1-phenyl-1H-pyrazol-5-yl)methanone (7a) as a white solid (429 mg, 1.73 mmol, 86%).<\/p>\n<p>These compound has a wide range of applications.
