Procedure
4-{4-[2-[1-(2-Methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3-(2-trimethylsilanyl-ethoxymethyl)-3H-imidazol-4-yl]-phenyl}-piperazine-1-carboxylic acid benzyl ester (166 mg, 0.23 mmol) in EtOH (2.5 mL) was treated with 20% PdOH/C (60 mg) and placed under an atmosphere of H2. The reaction was stirred for 18 hours and filtered through a CELITE plug to afford crude (2-methyl-1-{2-[5-(4-piperazin-1-yl-phenyl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-propyl)-carbamic acid methyl ester (120 mg), which was used without further purification: MS (ESI) m/z 585 [M+H]+.
