Procedure

tert-Butyl 2-[(7-benzyloxy-3-nitroquinolin-4-yl)amino]ethylcarbamate (40.0 g, 91.22 mmol) was dissolved in ethyl acetate (550 mL) and transferred to a Parr hydrogenation vessel charged with 5% platinum on carbon (10.68 g, 54.73 mmol, 0.03 eq). The vessel was purged with nitrogen gas and placed under hydrogen pressure (30 psi, 2.07×105 Pa) overnight. The catalyst was removed by filtration through a layer of CELITE filter aid, and the filter cake was rinsed with methanol and dichloromethane. The filtrate was concentrated under reduced pressure to provide 35.25 g tert-butyl 2-[(3-amino-7-benzyloxyquinolin-4-yl)amino]ethylcarbamate.
