Procedure

N-[(1R)-2-{[tert-Butyl(dimethyl)silyl]oxy}-1-({[tert-butyl(dimethyl)silyl]oxy}methyl)-2-methylpropyl]-3-nitroquinolin-4-amine (6.51 g, 12.5 mmol) was dissolved in 75 mL toluene and the solution was placed in a pressure bottle. Platinum on carbon (5%, 2.0 g) was then added and the reaction mixture was shaken under H2 at 48 PSI (3.3×105 Pa). After 6 hours, the reaction mixture was filtered through a pad of CELITE filter agent. The pad was rinsed with toluene and 2-propanol and the combined filtrates were concentrated under reduced pressure to give N4-[(1R)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-({[tert-butyl(dimethyl)silyl]oxy}methyl)-2-methylpropyl]quinoline-3,4-diamine (6.12 g) as a brown foam.
