In 5.0 mL of ethyl acetate was dissolved 0.63 g of 1-{2-[2-(1-benzothiophen-4-yl)ethoxy]ethyl}-3-pyrrolidinol, and to the solution was added 0.80 mL of a 3.25 mol/L dried hydrogen chloride-ethyl acetate solution. The resulting mixture was stirred at room temperature for 1 hour and then at 5° C. for 1 hour, after which the crystals precipitated were collected by filtration. The crystals precipitated were washed with ethyl acetate and then dried to obtain 0.43 g of 1-{2-[2-(1-benzothiophen-4-yl)ethoxy]ethyl}-3-pyrrolidinol hydrochloride as colorless crystals.
