반응 단계

To a solution of diethyl phosphono acetic acid (8.0 ml) in 1,2-dimethoxyethane (80 ml) was added sodium hydride (60% in oil, 1.4 g) at 0° C. under N2. After being stirred for 1 hour at ambient temperature, to the solution was added a solution of 2-(3-methoxyphenyl)cyclopentanone (4.5 g) in 1,2-dimethoxyethane (20 ml). After being stirred for 12 hours, the reaction mixture was poured into a mixture of ethyl acetate and water. The organic layer was washed with saturated sodium bicarbonate aqueous solution and brine. The dried solvent was concentrated and the obtained residue was purified by column chromatography on silica gel to give ethyl [2-(3-methoxyphenyl)cyclopentylidene]acetate (5.0 g).
