Procedure

(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), 250 mg) and 4-bromo-2-methoxypyridine (91 mg) in acetonitrile (8 mL) were treated with aqueous sodium carbonate solution (2M, 0.5 mL) and nitrogen was bubbled through the mixture. 1,1 bis(Di-tert-butylphosphino)ferrocene palladium dichloride (5 mg) was added and the mixture was heated at 85° C. for 18 h. The mixture was evaporated onto silica and purified by chromatography on silica eluting with ethyl acetate to afford the sub-titled compound (214 mg).
