A suspension of 1-[1-(4-fluorophenethyl)piperidin-4-yl]-6-[(isobutylcarbamoyl)methyl]indoline (0.07 g) obtained in Example 152 and active manganese dioxide (0.07 g) in chloroform (30 ml) was vigorously stirred at 50° C. overnight. Then the reaction mixtures were filtered through celite and the residue was washed with chloroform. After concentrating the filtrate under reduced pressure, the residue was recrystallized from chloroform/hexane to give the title compound (0.05 g) as a white powder (yield: 70.0%).
