Reaction Steps

(S)-tert-Butyl 4-(1-amino-3-(4-iodophenyl)-1-oxopropan-2-ylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 1, step (iii), 300 mg) in acetonitrile (7 mL) under nitrogen was treated with 4-(methylsulfonyloxy)phenylboronic acid (125 mg) followed by aqueous sodium carbonate (2M, 0.58 mL). Nitrogen was bubbled through the mixture and 1,1 bis(di-tert-butylphosphino)ferrocene palladium dichloride (5 mg) was added. The mixture was stirred at 85° C. for 25 h. The solvent was partially evaporated and then purified by chromatography on silica using ethyl acetate 50-100% isohexane as eluent to afford the sub-titled compound as a white solid (234 mg).
