The reaction mixture was cooled down to room temperature, to which water and toluene were then added, followed by adjustment to pH 1.0 using hydrochloric acid. The aqueous layer was separated, adjusted to pH 10.0 using a 20% sodium hydroxide aqueous solution, and stirred at room temperature for 15 minutes and then under cooling with ice for 30 minutes. The precipitate was collected by filtration and washed with water and toluene to provide 52.3 g of 4-{3-[4-(3-hydroxypropyl)-1-piperidinyl]propoxy}benzonitrile as white solid form.
