Procedure

A mixture of 40.5 g of 3-chloro-4-cyclohexylphenylacetic acid ethyl ester and 16 g of acrylic acid ethyl ester is added dropwise to a solution of 3.6 g of sodium in 60 ml of ethanol. The solution is refluxed overnight and then poured into a mixture of 10 ml of glacial acetic acid and 170 ml of ice water. The ethanol is distilled off and the residue extracted with ethyl acetate and evaporated; the residue is distilled under a high vacuum, to yield 24.3 g of 2-(3-chloro-4-cyclohexylphenyl)-glutaric acid diethyl ester boiling at 203°-205°C under 0.4 mm Hg pressure.
