tert-Butyl [4-(7-benzyloxy-3-nitroquinolin-4-ylamino)butyl]carbamate (39.92 g, 85.57 mmol) was dissolved in toluene (1700 mL) and added to a Parr vessel charged with 5% platinum on carbon (3.9 g) and a small volume of toluene. The vessel was placed under hydrogen pressure (50 psi, 3.4×105 Pa). The hydrogen was replaced three times, and the reaction was shaken overnight. The reaction mixture was filtered through a layer of CELITE filter aid, and the filter cake was washed with ethanol (700 mL). The filtrate was concentrated under reduced pressure to provide 28.62 g of tert-butyl {4-[3-amino-7-(benzyloxy)quinolin-4-ylamino]butyl}carbamate as a brown solid.
