Participants

Reaction Steps

In 1 mL of ethyl acetate is dissolved 0.58 g of 2-[{2-[2-(2-fluorobenzo[b]thiophen-5-yl)ethoxy]-ethyl}-(methyl)amino]-1-ethanol, to which is added 1 mL of a solution of 0.18 g of oxalic acid in ethyl acetate. The mixture is stirred at ambient temperature for 2 hours. The deposited crystal is collected by filtration, washed with ethyl acetate and dried to obtain 0.61 g of 2-[{2-[2-(2-fluorobenzo[b]-thiophen-5-yl)ethoxy]ethyl}(methyl)amino]-1-ethanol oxalate.
