Reaction Steps

In 2 mL of ethyl acetate is dissolved 0.46 g of N-[3-(2-benzo[b]thiophen-5-ylethoxy)propyl]-N,N-diethylamine, to which is added 2.5 mL of a solution of 0.15 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 0.47 g of N-[3-(2-benzo[b]thiophen-5-ylethoxy)propyl]-N,N-diethylamine oxalate.
