Participants

Reaction Steps

In 20 mL of ethanol is dissolved 12.69 g of 2-{[2-(2-benzo[b]thiophen-5-ylethoxy)ethyl](methyl)-amino}-1-ethanol. Then, 5.01 g of fumaric acid is added to the solution and heated. The solvent is distilled off under reduced pressure, 100 mL of acetone and 100 mL of diethyl ether are added to the residue, and the mixture thus obtained is stirred at ambient temperature for 2 hours. After stirring the mixture at 5° C. for an additional one hour, the deposited crystal is collected by filtration, washed with 1:1 mixture of diethyl ether and acetone, and dried to obtain 15.03 g of 2-{[2-(2-benzo[b]thiophen-5-ylethoxy)ethyl](methyl)amino}-1-ethanol fumarate.
