Reaction Steps

In 8 mL of N,N-dimethylformamide is dissolved 0.80 g of 2-(2-benzo[b]thiophen-5-ylethoxy)ethyl methanesulfonate, to which are added 0.73 mL of dipropylamine and 0.74 g of potassium carbonate. The resulting mixture is stirred at 80° C. for 3 hours. The reaction mixture is introduced into a mixture of water and ethyl acetate, and the organic layer is separated. The organic layer is washed with water and saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, the solvent is distilled off under reduced pressure, and the residue is purified by column chromatography (eluent:chloroform:methanol=10:1). Thus, 0.60 of N-[2-(2-benzo[b]thiophen-5-ylethoxy)ethyl]-N,N-dipropylamine is obtained as an oily product.
