The resulting solution was added to 20 mL of 3N hydrochloric acid. The aqueous layer was extracted with diethyl ether, which was added to the organic layer, and the organic layer was washed with a saturated salt solution and then dried over anhydrous magnesium sulfate. The solvent was distilled off to obtain 6.42 g of 3-((4-propylcyclohexyl)phenyl)phenyl propanoate (2).
