실험 절차
Platinum oxide (0.2 g, 0.82 mmol) was added as a slurry in ethanol to a solution of 3-cyclopentylpyridine (1 g, 6.8 mmol) in ethanol (15 ml) and concentrated hydrochloric acid (1 ml). The mixture was hydrogenated in a Parr apparatus at 50 psi for 18 hours then filtered through Celite. The filtrate was concentrated in vacuo and the residue partitioned between 10% aqueous sodium carbonate solution and ethyl acetate. The organic layer was dried (MgSO4) and concentrated in vacuo to give the title compound (0.87 g, 84%).
