Reaction Steps

10 ml of tetrahydrofuran was cooled to −78° C., 5.11 ml of n-butyllithium (1.6 M, hexane solution) was added thereto, and the mixture was stirred. A solution of 2.000 g of (2-cyclohexylmethyloxy)bromobenzene dissolved in 5 ml of tetrahydrofuran was added dropwise thereinto. After one hour, a solution of 1.93 g of 1-benzyl-4-piperidineacetaldehyde dissolved in 5 ml of tetrahydrofuran was added dropwise thereinto, and the mixture was further stirred for one hour. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and brine, and then dried over anhydrous magnesium sulfate. The solvent was evaporated, and the crude product was purified by NH form silica gel column chromatography (n-hexane:ethyl acetate=4:1), to give 2.986 g of the title compound as a colorless oil.
