Procedure

To an N,N-dimethylformamide (150 mL) solution of 10.2 g of 4-[3-(4-piperidinyl)propoxy]benzonitrile were sequentially added 11.2 g of potassium carbonate and 9.72 g of 4-(3-bromopropoxy)benzonitrile at room temperature, which was then stirred at the same temperature for 18 hours. Toluene and water were added to the reaction mixture. The precipitate was collected by filtration to provide 13.7 g of 4-(3-{4-[3-(4-cyanophenoxy)propyl]-1-piperidinyl}propoxy)benzonitrile as white solid form.
