In 5.0 mL of ethyl acetate was dissolved 0.99 g of (3R)-1-{2-[2-(1-benzothiophen-3-yl)ethoxy]ethyl}-3-pyrrolidinol, and to the solution was added 1.10 mL of a 3.25 mol/L dried hydrogen chloride-ethyl acetate solution, after which the resulting mixture was stirred at room temperature for 1 hour. Then, the solvent was distilled off under reduced pressure to obtain 1.05 g of (3R)-1-{2-[2-(1-benzothiophen-3-yl)ethoxy]ethyl}-3-pyrrolidinol hydrochloride as a light-yellow oil.
