Procedure

To a Pressure reaction bottle was added 5.0 g of 8-nitroquinaldine, 0.5 g 5% palladium on carbon, and 150 ml ethanol. The mixture was purged with hydrogen and then hydrogenated under 40 psi hydrogen for 16 hours. The catalyst was filtered off on a bed of celite. The solvent was removed, resulting in 4.2 g of a dark oil.
