1,1-Dimethylethyl N-{4-[(3-nitro[1,5]naphthyridin-4-yl)amino]butyl}carbamate (42.7 g, 0.12 mole), platinum on carbon (2 g) and ethyl acetate (500 mL) were combined and then hydrogenated on a Parr apparatus at 30 psi (2.1 Kg/cm2) hydrogen pressure for 1 hour. The catalyst was removed by filtration and rinsed with ethyl acetate. The filtrate was concentrated under vacuum to provide 1,1-dimethylethyl N-{4-[(3-amino[1,5]naphthyridin-4-yl)amino]butyl}carbamate as a bright yellow-orange solid.
