Procedure

95 mg of Sodium tetrahydroborate was added to a solution of tert-butyl 2-(2-chlorophenyl)ethyl[5-(1,3-dimethyl-2-oxo-2,3-dihydro-1H-benzimidazol-5-yl)-5-oxopentyl]carbamate obtained in Reference Example 60 in methanol (10 ml) at room temperature. After stirring at room temperature for 2 hours, 20 ml of an aqueous saturated ammonium chloride solution was added. The liberated oil was extracted with chloroform (30 ml×2), dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound as a pale yellow oil (1.25 g).
