Procedure

118 mg (0.82 mmol) of 1-chloroethyl chloroformate were added to a solution of 550 mg (0.79 mmol) of 3-{2-[(R)-3-(4-benzylpiperazin-1-yl)-pyrrolidin-1-yl]-2-oxo-1-phenylethyl}-5-chloro-1-(4-methoxybenzenesulfonyl)-1,3-dihydrobenzimidazol-2-one (Example 142) in 5 ml dry dichloromethane while stirring at 0° C. The reaction mixture was subsequently stirred at 0° C. for 1 h and then at room temperature overnight. The solvent was removed in vacuo, and the residue was dissolved in 20 ml of methanol.
