Procedure
1-[1-(4-Fluorophenethyl)piperidin-4-yl]-6-(2-pyrrolidon-1-yl) methylindoline (80 mg) obtained in Example 202, activated manganese dioxide (400 mg) and chloroform (10 ml) were treated as in Example 285 to give the title compound (69 mg) as an oil. This oil was then crystallized from ethyl acetate by using oxalic acid (13 mg) to give the oxalate (54 mg) of the title compound as a white powder (yield: 61%).
