A mixture of 4-(3-pyridyl)cyclohex-3-en-1-one ethylene acetal (4.80 g, 22.1 mmol) in EtOAc (50 mL) containing 10% Pd/C (458 mg) was hydrogenated under atmospheric pressure for 3 h. After filtration of the catalyst, the solution was concentrated in vacuo, to yield 4-(3-pyridyl)cyclohexanone ethylene acetal (4.81 g, 99%) as yellow solid.
