25 g | With (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; potassium acetate In dimethyl sulfoxide at 85℃; for 2 h; | 7-bromoindole (20 g, 0.102mol) was dissolved in DMSO (100mL) in an 1 L single neck flask, and bis(pinacolato)diboron (39 g, 0.153 mol), [1,1’-bis(diphenylphosphino)ferrocene]dichloropalladium (Pd(dppf)Cl2, 4 g, 0.005 mol),and potassium acetate (15 g, 0.153 mol) were added. The system was heated to 85 °C to react for 2 h. Water was addedto quench the reaction. The mixture was extracted with ethyl acetate for 3 times, dried over sodium sulfate, concentrated,and subjected to column chromatography to obtain the product (25 g, 0.103 mol). 1H NMR (400 MHz, CDCl3): δ 9.29(s, 1H), 7.82 (d, J = 7.9 Hz, 1H), 7.70 (d, J = 7.0 Hz, 1H), 7.32-7.29 (m, 1H), 7.21-7.14 (m, 1H), 6.62-6.57 (m, 1H), 1.44(s, 12H).
