Reaction Steps

A mixture of 3-(2-pyridyl)-2-cyclopenten-1-one (1.43 g, 8.98 mmol) and 10% Pd/C (142 mg) in EtOH (30 mL) was stirred under hydrogen atmosphere (0.3 MPa) for 6.5 h. The catalyst was removed by filtration over Celite and the filtrate was concentrated in vacuo. The crude product was purified by column chromatography (Hexane/EtOAc=1/1) to yield 3-(2-pyridyl)cyclopentan-1-one (3.26 g, 94%) as colorless oil.
