A mixture of 4-[(3-nitro[1,5]naphthyridin-4-ylamino)methyl]tetrahydropyran-4-ol (12.2 g), 5% platinum on carbon (1.22 g), and ethyl acetate (160 mL) was placed under hydrogen pressure (40 psi, 2.8×105 Pa) for 3 hours. The reaction mixture was filtered through a layer of CELITE filter aid and the filter cake was rinsed with 1:1 ethyl acetate:methanol (150 mL). The filtrate was concentrated under reduced pressure to provide 12.66 g of 4-[(3-amino[1,5]naphthyridin-4-ylamino)methyl]tetrahydropyran-4-ol as a thick semi-solid.
