Procedure

To a solution of acetic acid 3-acetoxy-2-(4-{[4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carbonyl]-amino}-3-cyclohex-1-enyl-phenyl)-propyl ester (as prepared in the previous step, 580 mg, 1.00 mmol) in i-PrOH (15 mL), 2N NaOH (1 mL, 2 mmol) was added. The reaction mixture was stirred at RT for 1 h, and DCM (200 mL) and water (200 mL) were added. The organic layer was separated, dried (Na2SO4) and concentrated. The residue was purified on silica (40% EtOAc-hexane) to obtain the title compound (312 mg, 63%): Mass spectrum (ESI, m/z): Calcd. for C26H36N4O4Si, 497.2 (M+H). found 497.0.
