A solution of 1-(7-bromo-3-nitroquinolin-4-ylamino)-2-methylpropan-2-ol (27.78 g, 81.66 mmol) in acetonitrile (1.2 L) was added to a Parr vessel charged with 5% platinum on carbon (0.84 g), and the reaction was placed under hydrogen pressure (50 psi, 3.4×105 Pa) for two days. The reaction mixture was filtered through a layer of CELITE filter aid, and the filter cake was washed with ethanol (1 L). The filtrate was concentrated under reduced pressure to provide 21.70 g of 1-(3-amino-7-bromoquinolin-4-ylamino)-2-methylpropan-2-ol as a yellow oil.
