실험 절차

A mixture of 3-(benzyloxy)-N-(cyclohexylmethyl)-1-cyclopropyl-6-methyl-4-oxo-1,4-dihydropyridine-2-carboxamide (2.0 g, 4.8 mmol), Pd/C (10% wet, 0.45 g) in ethanol (150 mL) was hydrogenated in a Parr apparatus at 50 psi of hydrogen pressure for 16 h. The reaction mixture was filtered over a pad of Celite® and the Celite® was thoroughly washed with EtOH (25 mL). Evaporation of the solvent afforded a pale pink solid. The solid was dissolved in hot methanol, then cooled to RT as solid product precipitated out. The solid was collected by suction filtration. The mother liquor was concentrated in vacuo and the residual solid was again dissolved in hot methanol and cooled to RT to precipitate out the product, which was then collected. This process was repeated one more time. The three combined white solid fractions weighed 0.95 g (63% yield).
