Procedure

A solution of 1-[1-(4-fluorophenethyl)piperidin-4-yl]-6-cyanoindoline (1.0 g) in conc. sulfuric acid (1 l) was heated at 50° C. for 2 hr. After diluting with ice water, the reaction solution was basified with a conc. aqueous solution of sodium hydroxide. Then ethyl acetate was added thereto and the layers were separated. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give the title compound (0.81 g) as a white powder (yield: 77%).
