実験手順

To a solution of (+)-2-[2-(N,N-dimethylamino)ethyl]-6-hydroxytetralin (0.217 g) in DMF (5 ml) was added sodium hydride (60% in oil, 0.052 g) at room temperature. The reaction mixture was stirred at 50° C. for one hr and cooled to 0° C. A solution of 2-chloromethylbenzofuran (0.187 g) in THF (5 ml) was added to the solution. The reaction mixture was stirred at 0° C. for one hr, diluted with water, and extracted with ethyl acetate. The organic layer was washed with water and saturated aqueous sodium chloride, dried, and concentrated. The residue was purified by alumina column chromatography (eluent:ethyl acetate:hexane=1:4) and recrystallized from ethyl acetate-hexane to obtain the titled compound (17 mg).
