N-[(4-chlorophenyl)methyl]-4-hydroxy-6-nitro-3-quinolinecarboxamide (500 mg) is suspended in 50 mL of freshly degassed dimethylformamide and treated with 0.5 mL of 50% Raney nickel in water (Aldrich). The mixture is agitated under 45 psi hydrogen pressure for 24 h, and then it is filtered through celite. The solvent is removed by evaporation at reduced pressure and the residue is suspended in 5 mL of absolute ethanol and it is collected by filtration. After drying at 0.1 torr/100 ° C./1.5 h, the product is obtained as 387 mg of a pale yellow powder.
