Procedure

To a solution of 2-oxo-3-{2-oxo-1-phenyl-2-[(S)-3-(4-propyl-piperazin-1-yl)-pyrrolidin-1-yl]-ethyl}-2,3-dihydro-1H-benzoimidazole-5-carbonitrile (70 mg, 0.15 mmol), DMAP (catalytic amount) and 2-methoxybenzenesulfonyl chloride (37 mg, 0.18 mmol) in CH2Cl2 (3 mL) SilicaBond-diethylamine resin (Silicycle; 1.04 mmol/g; 570 mg, 0.59 mmol) was added. The reaction mixture was agitated at room temperature for 24 hours, filtered and concentrated in vacuo. The residue was purified by flash chromatography on silica gel using 4% methanol in CH2Cl2 as eluent to afford 1-(2-methoxy-benzenesulfonyl)-2-oxo-3-{2-oxo-1-phenyl-2-[(S)-3-(4-propyl-piperazin-1-yl)-pyrrolidin-1-yl]ethyl}-2,3-dihydro-1H-benzoimidazole-5-carbonitrile (55 mg, 57%) as a white solid.
