Mode opératoire

In 2.0 mL of ethyl acetate was dissolved 0.48 g of 1-{2-[2-(1-benzothiophen-6-yl)ethoxy]ethyl}-3-pyrrolidinol, and to the solution was added a solution of 0.15 g of oxalic acid in 2.8 mL of ethyl acetate. 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 0.42 g of 1-{2-[2-(1-benzothiophen-6-yl)ethoxy]ethyl}-3-pyrrolidinol oxalate as colorless crystals.
