Procedure

5 mg of dimethylaminopyridine and 0.029 ml of trimethylsilyl isocyanate were added to a methylene chloride (1 ml) solution of 17.1 mg of 5-(4-methanesulfonyl-phenoxy)-2-pyridin-2-yl-6-pyrrolidin-2-yl-1H-benzimidazole obtained in Example 162 (step 7), and the reaction liquid was stirred overnight at room temperature. Water was added to the reaction liquid, and extracted with ethyl acetate, and then washed with saturated saline. After dried and concentrated, the resulting residue was purified through reversed-phase middle-pressure liquid chromatography [ODS-AS-360-CC (by YMC), mobile phase: water-acetonitrile-0.1% trifluoroacetic acid], and the resulting fraction was diluted with ethyl acetate, washed with aqueous saturated sodium bicarbonate and saturated saline in order, and dried with anhydrous sodium sulfate. The solvent was evaporated away under reduced pressure to obtain the entitled compound as a white solid.
