Reaction Conditions

Reaction Steps

A suspension of 1-[1-(4-fluorophenethyl)piperidin-4-yl]-6-[(cyclopropylcarbamoyl)methyl]indoline (0.04 g) obtained in Example 154 and active manganese dioxide (0.04 g) in chloroform (30 ml) was vigorously stirred at 50° C. for 10 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 (0.03 g) as a white powder (yield: 81.9%).
