実験手順

A mixture of EXAMPLE 1E (1.2 g), 1.0 M 4,4,5,5-tetramethyl-1,3,2-dioxaborolane in tetrahydrofuran (4.24 mL), triethylamine (0.92 mL), and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane (0.087 g) in CH3CN (15 mL) was heated at 100° C. under microwave conditions (Biotage) for 30 minutes. After cooling, the reaction mixture was partitioned between water and ethyl acetate. The organic layer was extracted with additional ethyl acetate twice. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified by flash column chromatography on silica gel to provide the title compound.
