実験手順

(S)-tert-butyl 4-(1-amino-3-(4-iodophenyl)-1-oxopropan-2-ylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 1, step (iii), 300 mg), 3-(methylsulfonyloxy)phenylboronic acid (Example 12, step (i), 125 mg) and potassium carbonate (240 mg) in acetonitrile (10 mL) and water (5 mL) were stirred and heated at 90° C. under a nitrogen atmosphere with 1,1 bis(di-tert-butylphosphino)ferrocene palladium dichloride (11 mg). After 20 h the reaction was complete and the solvents were removed under reduced pressure. The residue was partitioned between water (100 mL) and ethyl acetate (100 mL), and the organic phase collected and dried over magnesium sulfate. The extract was concentrated to a gum and the crude material purified by chromatography on silica eluting with ethyl acetate to afford the sub-titled is compound (120 mg).
