N-[(1S)-2-{[tert-Butyl(dimethyl)silyl]oxy}-1-(4-{[tert-butyl(dimethyl)silyl]oxy}benzyl)ethyl]-3-nitroquinolin-4-amine (25.24 g, 44.45 mmol) was dissolved in 300 mL of toluene and the solution was placed in a pressure bottle. Platinum on carbon (5%, 1.47 g) was then added and the reaction mixture was shaken under H2 at 35 PSI (2.4×105 Pa). After 20 hours, the reaction mixture was filtered through a pad of CELITE filter agent. The pad was rinsed with toluene and acetonitrile and the combined filtrates were concentrated under reduced pressure to give N4-[(1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-(4-{[tert-butyl(dimethyl)silyl]oxy}benzyl)ethyl]quinoline-3,4-diamine (23.46 g) as an orange foam.
