Reaction Conditions

Reaction Steps

A suspension of 1-[1-(4-fluorophenethyl)piperidin-4-yl]-6-[(n-propylcarbamoyl)methyl]indoline (0.04 g) obtained in Example 150 and active manganese dioxide (0.08 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 (0.03 g) as white needles (yield: 84.6%).
