Reaction Steps

tert-Butyl [2-(6-benzyloxy-3-nitroquinolin-4-ylamino)-1,1-dimethylethyl]carbamate (13.75 g), 5% platinum on carbon (1.03 g), and acetonitrile (250 mL) were combined. The mixture was shaken overnight under 50 psi (3.4×105 Pa) of hydrogen. The reaction was filtered through CELITE filter agent, and the filter pad was rinsed with acetonitrile. The filtrate was concentrated under reduced pressure. Residual water was removed by an azeotrope with toluene. Removal of all volatiles under reduced pressure provided 13.34 g of crude tert-butyl [2-(3-amino-6-benzyloxyquinolin-4-ylamino)-1,1-dimethylethyl]carbamate as a brown foam.
