実験手順

Ethyl 7-(3,5-bis(trifluoromethyl)phenoxy)heptanoate was added to 95% ethanol and dissolved by reflux. The solution was then added with sodium hydroxide and further refluxed. The resulting crystals were filtered, washed with ethanol, and then added with dichloromethane and 1N hydrochloric acid. The solution was extracted twice with dichloromethane. After the organic layer was dried over anhydrous magnesium sulfate, the solvent was removed and the residue was purified by silica gel column chromatography to obtain 7-(3,5-bis(trifluoromethyl) phenoxy) heptanoic acid.
