A mixture of (S)-tert-butyl 4-(1-cyano-2-(4-iodophenyl)ethylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 15, step (i), 260 mg), potassium acetate (153 mg) and 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)isoindolin-1-one (162 mg) in acetonitrile (10 mL) and water (5 mL) under a nitrogen atmosphere, was treated with 1,1 bis(di-tert-butylphosphino)ferrocene palladium dichloride (10 mg) and the mixture stirred and heated at 90° C. for 18 h. The reaction mixture was cooled to room temperature and diluted with water. The products were extracted into ethyl acetate (2×100 mL) and the combined extracts dried over magnesium sulphate and concentrated to dryness. The residue was purified by chromatography on silica eluting with ethyl acetate to afford the sub-titled compound (160 mg).
