Methyl 4-allyl-3-hydroxyoctanoate (6.8 g, 31.7 mmol) was dissolved in a 2 N potassium hydroxide-methanol solution (20 mL), and the solution was stirred overnight at room temperature. The reaction solution was concentrated, then diluted with water, and washed with ether. The aqueous solution was made acidic using hydrochloric acid, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated saline and dried over anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure to obtain the compound of interest as an oil substance (6.0 g, 30 mmol). This compound was used in the next reaction without being purified.
