Participants

Reaction Steps

0.5 g (1.84 mmol) of 4-[1-(2-ethoxy-ethyl)-indol-3-yl]-piperidine and 0.55 g (2.4 mmol) of ethyl 4-chloro-ethoxy-benzoate were disolved in 6 mL of 4-methyl-2-butanone and 0.38 g (2.76 mmol) of potassium carbonate were added. The mixture was refluxed for 18 hours and after cooling, water was added, the organic layer separated, washed with water and brine. The solvent was distilled off. The obtained crude was disolved in 3 mL of ethyl alcohol 96% and 2 mL of a 2N aqueous sodium hydroxide solution were added. After stirring at room temperature for 18 hours the mixture was neutralised with a sulphuric acid solution 10%. The formed solid (0.390 g, 65% yield) was collected, washed with water and dried.
