Conditions

Temperature: 100 °C

Procedure

To a solution of EXAMPLE 71C (500 mg), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane (46.8 mg) and triethylamine (0.399 mL) in acetonitrile (7 mL) and tetrahydrofuran (3.5 mL) was added 4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.416 mL). The mixture was heated at 100° C. in a Biotage Initiator microwave reactor for 30 minutes, cooled, diluted with ethyl acetate, and washed with brine. The organic layer was concentrated. The residue was purified by flash chromatography, eluting with 0-17% ethyl acetate in dichloromethane to provide the title compound.
