실험 절차

(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) in acetonitrile (8 mL) with 4-(4-bromophenylsulfonyl)morpholine (148 mg) was treated with aqueous sodium carbonate (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 under nitrogen. The reaction mixture was evaporated onto silica and purified by chromatography on silica eluting with ethyl acetate/isohexane (50:50 to 100:0) to afford the sub-titled compound (240 mg).
