Procedure
A suspension of 0.40 g (1.0 mmol) 1-[1-(6-chloro-1H-indole-3-carbonyl)-piperidin-4-yl]-1,3-dihydro-indol-2-one, 0.16 g (1.1 mmol) 1-chloro-2-dimethylaminoethane hydrochloride and 0.69 g (2.1 mmol) cesium carbonate in 10 ml acetonitrile was heated at 50° C. over night. After cooling to room temperature the reaction mixture was diluted with a 0.5 M aqueous solution of sodium hydroxide and extracted with three portions of ethyl acetate. The combined organic extracts were washed with brine, dried over sodium sulfate and concentrated in vacuo. Flash chromatography gave 0.18 g (39%) of the title compound.
