Reaction Steps
Potassium hydroxide (14 g) was added to a solution of diethyl 2-ethyl-2-(2-(4-(4-phenylbutyloxy)phenyl)ethyl)malonate (46 g) in ethanol (300 ml) and the mixture was refluxed under heating for 3.5 hours. The reaction mixture was poured into water and washed with isopropyl ether. After being acidified to pH 1 with concentrated hydrochloric acid, the aqueous layer was extracted with ethyl acetate. The ethyl acetate layer was washed with a saturated brine and dried over anhydrous sodium sulfate, and the solvent was distilled away under reduced pressure to give the subject compound (23 g).
