実験手順
Suspension of 11.8 g of 4-chlorobenzyltriphenyl-phosphonium bromide in 100 ml of THF was stirred under nitrogen gas stream, and 2.8 g of potassium-t-butoxide was added to the suspension at room temperature. After stirred at room temperature for 1 hour, a solution of 7 g of the 4-(2-(trans-4-(4-n-propylphenyl)cyclohexyl)ethyl)benzaldehyde in 50 ml of THF was added dropwise. After stirred at room temperature for 2 hours, 300 ml of water was added and extracted with 300 ml of ethyl acetate. Organic layer was washed with water and dried over anhydrous magnesium sulfate, the solvent was distilled off under a reduced pressure, and then 200 ml of heptane was added. Precipitate thus separated was filtered off, and subjected to a column chromatography over a silica gel by using ethyl acetate/heptane (1/5) as an eluent. Solvent was distilled off under a reduced pressure to obtain 5.6 g 4-(2-(4-(2-(trans-4-(4-n-propylphenyl)cyclohexyl)ethyl)phenyl)ethenyl)chlorobenzene.
