YieldReaction ConditionsOperation in experiment
48.15% With (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; potassium acetate In dimethyl sulfoxide at 80℃; for 8 h; Inert atmosphere A mixture of 4-iodo-1-phenyl-1H-pyrazole (706 mg, 2.59 mmol) , potassium acetate (762 mg, 7.76 mmol) , bis (pinacolato) diboron (860 mg, 3.37 mmol) and Pd (dppf) Cl2(212 mg, 0.26 mmol) was suspended in DMSO (15 mL) . The system was exchanged with N2. The mixture was stirred at 80 for 8 h. The reaction mixture was diluted with water (60 mL) . The resulting mixture was extracted with DCM (50 mL × 3) . The combined organic layers were washed with saturated aqueous NaCl (15 mL) , dried over anhydrous Na2SO4and concentrated in vacuo. The residue was purified by silica gel column chromatography eluted with PE/EtOAc (v/v) 20/1 to give a yellow solid product (340 mg, 48.15) .[1650]MS (ESI, pos. ion) m/z: 271.05 [M+1]+.
