Conditions

Temperature: 50 °C

Procedure

A suspension of 1-[1-(4-fluorophenethyl)piperidin-4-yl]-6-(ethylcarbamoylmethyl)indoline (0.41 g) obtained in Example 149 and active manganese dioxide (0.40 g) in chloroform (30 ml) was vigorously stirred at 50° C. for 6 hr. 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 (0.33 g) as white needles (yield: 89.5%).
