Ethyl Acetate → 1-Benzyl-3-[4-(4-ethoxyphenyl)-4-methylpent-1-en-1-yl]benzene

Participants

Reaction Steps

To 5 ml of dry ether was added 0.1 g of lithium aluminum hydride, and thereinto was added a solution of 0.7 g of aluminum chloride in 10 ml of dry ether. A solution of 0.54 g of 1-(3-benzoylphenyl)-4-(4-ethoxyphenyl)-4-methyl-1-pentene (prepared according to (1) of Synthesis Example 12) in 2 ml of dry ether was added dropwise into the mixture, and refluxed for 30 minutes. After cooling to room temperature, ethyl acetate was added dropwise into the mixture. And the mixture was poured into ice water, and extracted with benzene. The benzene extract was washed with water and dried, and evaporated under reduced pressure, and purified by column chromatography on silica gel (1:2 mixed solvent of benzene and hexane) to give 0.45 g of the desired product.
