실험 절차
A 2-L, stainless-steel, Parr vessel was charged with platinum on carbon (5%, 4.0 g) and 10 mL of acetonitrile. A solution of 7-bromo-N-((1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethyl)-3-nitroquinolin-4-amine (40.5 g, 92.0 mmol) dissolved in 1 L of acetonitrile was then added. The reaction mixture was placed on Parr apparatus and shaken under H2 at 45 PSI (3.1×105 Pa) for 6 hours at ambient temperature. The reaction mixture was then filtered through a pad of CELITE filter agent. The pad rinsed with an additional 200 mL of acetonitrile and the combined filtrates were concentrated under reduced pressure to give 33.4 g 7-bromo-N4-((1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethyl)quinoline-3,4-diamine as a yellow solid.
