To a solution of 1.58 g (4.35 mmol) of 4-hydroxy-3-[10-(4-chlorophenyl)-1-oxodec-9-enyl]-2(5H)-furanone in 100 mL of ethyl acetate is added 250 mg of 5% palladium on carbon and subjected to atmospheric hydrogenation using a balloon to deliver the hydrogen. After 1.5 hours, the reaction is worked up by filtering through Solka Flok. The filtrate is washed with copious amounts of ethyl acetate and concentrated in vacuo to give 1.05 g (66%) of pure 4-hydroxy-3-[10-(4-chlorophenyl)1-oxodecyl]-2(5H)-furanone.
