A Parr vessel was charged with a solution of tert-butyl N-{2-[(3-nitro[1,5]naphthyridin-4-yl)amino]-1,1-dimethylethyl}carbamate (12.62 g, 34.9 mmol) in acetonitrile (100 mL) and 5% Pt/C (2.00 g). The vessel was placed under hydrogen pressure (50 psi, 3.4×105 Pa) until hydrogen uptake ceased. The reaction mixture was filtered through a layer of CELITE filter aid and the filter cake was rinsed with acetonitrile. The filtrate was concentrated under reduced pressure to provide 11.07 g of tert-butyl N-{2-[(3-amino[1,5]naphthyridin-4-yl)amino]-1,1-dimethylethyl]carbamate as a bright yellow foam.
