In 2.5 mL of ethyl acetate is dissolved 1.06 g of N,N-diethyl-N-{2-[2-(1-naphthyl)ethoxy]ethyl}-amine, to which is added 3.0 mL of a solution of 0.35 g of oxalic acid in ethyl acetate. The resulting mixture is stirred at ambient temperature for 2 hours. The deposited crystal is collected by filtration, washed with ethyl acetate and dried to obtain 1.01 g of N,N-diethyl-N-{2-[2-(1-naphthyl)ethoxy]ethyl}-amine oxalate.
