실험 절차

A pressure bottle was charged with platinum on carbon (5%, 1.16 g) followed by a solution of N-((1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethyl)-2-chloro-5,6-dimethyl-3-nitropyridin-4-amine (4.79 g, 12.8 mmol) dissolved in 125 mL of toluene. 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 CH2Cl2. The combined filtrates were concentrated under reduced pressure to give N4-((1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethyl)-2-chloro-5,6-dimethylpyridine-3,4-diamine (4.39 g) as an orange oil.
