실험 절차

In 12 mL of N,N-dimethylformamide was dissolved 1.20 g of 5-[2-(3-chloropropoxy)ethyl]-1-benzothiophene, and 0.82 g of 3-pyrrolidinol and 1.30 g of potassium carbonate were added to the solution, after which the resulting mixture was stirred at 85° C. for 2.5 hours. After the reaction mixture was cooled, water and ethyl acetate were added thereto and the organic layer was separated. The organic layer was washed with water and then a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and then distilled under reduced pressure to remove the solvent. The residue was purified by a column chromatography (eluent; chloroform : methanol 20:1 to 10:1) to obtain 0.78 g of 1-{3-[2-(1-benzothiophen-5-yl)ethoxy]propyl}-3-pyrrolidinol as a colorless oil.
