Procedure
1,3-dihydro-4-(piperidin-3-yl)-2H-indole-2-one and n-propyl iodide in dimethylformaimide were reacted in the presence of sodium carbonate to obtain 1,3-dihydro-4-(1-propyl-piperidin-3-yl)-2H-indole-2-one. A solution of the latter in ether was admixed with an ether solution saturated with hydrogen chloride and the recovered product after crystallization from an isopropanol-methanol mixture melted at 260° C.
