Procedure

In 4.0 mL of ethyl acetate was dissolved 0.39 g of 1-{3-[2-(1-benzothiophen-5-yl)ethoxy]propyl}-N,N-dimethyl-3-pyrrolidinamine, 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. The crystals precipitated were collected by filtration, washed with ethyl acetate and then dried to obtain 0.32 g of 1-{3-[2-(1-benzothiophen-5-yl)ethoxy]propyl}-N,N-dimethyl-3-pyrrolidinamine dihydrochloride as colorless crystals.
