Versuchsvorschrift

In 20 mL of ethanol is dissolved 1.90 g of 5-{2-[2-(diethylamino)ethoxy]ethyl}-benzo[b]thiophen-2-carboxylic acid, to which is added 5.6 mL of 1.38 mol/L solution of dry hydrogen chloride in ethanol. The resulting mixture is stirred at ambient temperature for 2 hours, and diluted with 20 mL of ethyl acetate. The deposited crystal is collected by filtration, washed with ethyl acetate and dried to obtain 1.51 g of 5-{2-[2-(diethylamino)ethoxy]ethyl}-benzo[b]thiophene-2-carboxylic acid hydrochloride.
