Oxalic Acid → N-[2-(2-benzo[b]thiophen-5-ylethoxy)ethyl]-N,N-dipropylamine oxalate

Participants

Reaction Steps

In 1 mL of ethyl acetate is dissolved 0.60 g of N-[2-(2-benzo[b]thiophen-5-ylethoxy)ethyl]-N,N-dipropylamine, to which is added 2 mL of a solution of 0.18 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 0.56 g of N-[2-(2-benzo[b]thiophen-5-ylethoxy)ethyl]-N,N-dipropylamine oxalate.
