الإجراء التجريبي

0.71 g of 1-(2-(2-(1-benzothiophene-5-yl)ethoxy)ethyl)-3-pyrrolidinamine was dissolved in 3.0 ml of ethyl acetate. Thereafter, 4.0 ml of an ethyl acetate solution containing 0.44 g of oxalic acid was added to the obtained solution, and the obtained mixture was stirred at a room temperature for 1 hour and then at 5° C. for 1 hour. Thereafter, precipitated crystals were collected by filtration, washed with ethyl acetate, and then dried, so as to obtain 1.03 g of an achromatic crystal, 1-(2-(2-(1-benzothiophene-5-yl)ethoxy)ethyl)-3-pyrrolidinamine dioxalate.
