Procedure
To a solution of 5-chloro-2-(4-methoxyphenyl)-heptanoic acid methyl ester (0.26 g, 0.96 mmol) in 5 ml of DMF at 0° C. was added sodium hydride (0.6 g, 1.4 mmol). The reaction was stirred for 1 h at this temperature then quenched with 10 ml of water. The product was extracted into ethyl acetate (3×15 ml), washed with brine (20 ml), dried with magnesium sulfate and concentrated in vacuo to give a yellow oil. Silica gel chromatography eluting with hexane/ethyl acetate (4:1) gave 0.063 g of the title compound as a colorless oil.
