Reaction Steps

A mixture of tert-butyl 3-[(3-nitro[1,5]naphthyridin-4-yl)amino]propylcarbamate (20.0 g, 57.6 mmol), 5% platinum on carbon, and ethyl acetate was hydrogenated on a Parr apparatus for two hours at 30 psi (2.1×105 Pa). The mixture was filtered through CELlTE filter agent, which was rinsed afterwards with ethyl acetate (150 mL). The filtrate was concentrated to afford tert-butyl 3-[(3-amino[1,5]naphthyridin-4-yl)amino]propylcarbamate as a yellow foam, all of which was used in the next step.
