(S)-tert-Butyl 4-(1-amino-1-oxo-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propan-2-ylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 16, step (i), 300 mg), 6-bromo-2-methylisoindolin-1-one (Example 30, step (i), 131 mg) and potassium acetate (171 mg) in a mixture of acetonitrile (15 mL) and water (5 mL) was stirred under nitrogen at 90° C. with 1,1 bis(di-tert-butylphosphino)ferrocene palladium dichloride (378 mg). After 4 h the reaction mixture was cooled to room temperature and diluted with water (50 mL). The products were extracted with ethyl acetate (3×50 mL) and the combined extracts dried over magnesium sulfate and concentrated to afford the sub-titled compound (200 mg).
