実験手順
(S)-tert-Butyl 4-(1-amino-3-(3′-cyano-4′-methylbiphenyl-4-yl)-1-oxopropan-2-ylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 18, step (i), 154 mg) in dichloromethane (8 mL) was treated with Burgess' reagent (145 mg) and the mixture was stirred at room temperature for 18 h. The solvent was partially evaporated and the mixture was purified by chromatography on silica eluting with ethyl acetate/isohexane (1:1) to afford the sub-titled compound (127 mg).
