実験手順: In a 200-ml flask, 0.94g (9.35 mmol) of diisopropyl amine and 15 ml of tetrahydrofuran were placed and cooled to -50° C. Then 6.5 ml (10.3 mmol) of n-butyl lithium (15% n-hexane solution) was added thereto under nitrogen atmosphere. The resulting mixture was stirred for 10 minutes, and a solution of 1.0 g (9.35 mmol) of 4-ethylpyridine dissolved in tetrahydrofuran was added dropwise. After stirring for 30 minutes at -50° C., the reaction temperature was gradually raised up to -10° C., which was kept for 30 minutes, and lowered again to -50° C. A solution of 2.05 g (9.35 mmol) of 2-chlorophenethyl bromide dissolved in tetrahydrofuran was added dropwise to the reaction mixture, and after stirring for 30 minutes at -50° C., the temperature was raised up to room temperature. Subsequently, water was added, tetrahydrofuran was distilled away under reduced pressure, and the residue was extracted with ethyl acetate. The extract was washed with saturated brine, then dried over anhydrous sodium sulfate. Then, the solvent was distilled away under reduced pressure, to obtain an oil. Said oil was purified by silica gel column chromatography, to obtain 1.35 g of the desired compound (yield: 58.2%). was added dropwise After stirring for 30 minutes at -50° C. the reaction temperature was gradually raised up to -10° C., which was kept for 30 minutes lowered again to -50° C was added dropwise to the reaction mixture after stirring for 30 minutes at -50° C. the temperature was raised up to room temperature tetrahydrofuran was distilled away under reduced pressure the residue was extracted with ethyl acetate The extract was washed with saturated brine dried over anhydrous sodium sulfate Then, the solvent was distilled away under reduced pressure to obtain an oil was purified by silica gel column chromatography
