実験手順

0.80 g of 5-(2-(3-chloropropoxy)ethyl)-1-benzothiophene was dissolved in 8 ml of N,N-dimethylformamide. Thereafter, 1.20 g of N-(3-azetidinyl)acetamide was added to the obtained solution, and the obtained mixture was stirred at 90° C. for 12 hours. After cooling, water and ethyl acetate were added to the reaction mixture, and an organic layer was separated. The organic layer was successively washed with water and a saturated saline solution, and then dried over anhydrous magnesium sulfate. Thereafter, the solvent was distilled away under a reduced pressure. The residue was purified by column chromatography (eluent; chloroform:methanol=7:1), so as to obtain 0.39 g of a light yellow oil product, N-(1-(3-(2-(1-benzothiophene-5-yl)ethoxy)propyl)-3-azetidinyl)acetamide.
