N-{2-[(2,3-dimethyl-5-nitro-6-phenoxypyridin-4-yl)amino]-1,1-dimethylethyl}acetamide (2.40 g, 6.45 mmol) was dissolved in 20 mL of toluene and treated with 0.2 g of Pt (5% on carbon). The reaction mixture was then shaken under H2 (3 atm) for 24 h. Then reaction mixture was then treated with an additional 1.5 g of Pt (5% on carbon) and shaken an additional 8 h. The reaction mixture was then filtered through Celite, rinsing with toluene, and concentrated to give N-{2-[(3-amino-5,6-dimethyl-2-phenoxypyridin-4-yl)amino]-1,1-dimethylethyl}acetamide (1.80 g) as a colorless oil.
