Oxalic Acid → HCID 22666389, compound

Participants

Reaction Steps

In 2.5 mL of ethyl acetate is dissolved 0.90 g of N,N-diethyl-N-{2-[2-(6-fluorobenzo[b]thiophen-5-yl)ethoxy]ethyl}-amine, to which is added 2 ml of a solution of 0.27 g of oxalic acid in ethyl acetate. The resulting mixture is stirred at ambient temperature for 2 hours. The reaction mixture is diluted with 10 mL of diisopropyl ether, and the resulting crystalline precipitate is collected by filtration, washed with diisopropyl ether and dried. Thus, 0.83 g of N,N-diethyl-N-{2-[2-(6-fluorobenzo[b]thiophen-5-yl)ethoxy]ethyl}amine oxalate is obtained.
