실험 절차

(S)-tert-Butyl 4-(1-amino-3-(4-iodophenyl)-1-oxopropan-2-ylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 1, step (iii), 350 mg) in acetonitrile (7 mL) under nitrogen was treated with 4-(azetidin-1-ylsulfonyl)phenylboronic acid (163 mg) followed by sodium carbonate (0.677 mL). Nitrogen was bubbled through the mixture and 1,1 bis(di-tert-butylphosphino)ferrocene palladium dichloride (10 mg) was added. The mixture was stirred at 85° C. for 25 h. The solvent was partially evaporated and the solution was purified by chromatography on silica using ethyl acetate 50-100% in isohexane as eluent to afford the sub-titled compound as a solid (309 mg).
