Procedure

0.88 ml of triethylamine, 0.1 g of 10% palladium carbon were added to 20 ml of a solution of 0.86 g of 7-chloro-4-{4-[N-methyl-N-(2-phenylethyl)amino]-1-piperidinylcarbonyl}oxindole in ethanol. The mixture was subjected to hydrogenation at normal pressure at room temperature for 6 hours. The catalyst was removed by filtration. The filtrate was subjected to distillation to remove the solvent. The residue was dissolved in methylene chloride. The solution was water-washed, dried with anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by a silical gel column chromatography (eluant:methylene chloride/methanol=30/1). The product was converted into a hydrochloride in ethanol to obtain 0.19 g of 4-{4-[N-methyl-N-(2-phenylethyl)amino]-1-piperidinylcarbonyl}oxindole hydrochloride as a colorless amorphous.
