Procedure

(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 (28 mg, 0.047 mmol) and 2-(1-tert-butoxycarbonyl-pyrrolidin-2-yl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-4-carboxylic acid (20 mg, 0.047 mmol) in DMF (1 mL) were treated with HATU (20 mg, 0.052 mmol) and N-methyl morpholine (0.26 mL, 0.23 mmol). The mixture was stirred for 18 hours then diluted with EtOAc (25 mL), and washed with saturated NaHCO3 (3 10 mL), H2O (10 mL), and brine (10 mL). The solution was dried over MgSO4 to afford crude 2-[4-[4-(4-{2-[1-(2-methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3-methyl-3H-imidazol-4-yl}-phenyl)-piperazine-1-carbonyl]-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazol-2-yl}-pyrrolidine-1-carboxylic acid tert-butyl ester, which was used without further purification: MS (ESI) m/z 978 [M+H]+.
