Reaction Steps
A suspension of platinum oxide (36.9 mg) in a solution of 4-methyl-5-nitro-2-(trifluoromethyl)pyridine (369.4 mg, 0.162 mmol) in EtOH (12.7 mL) was stirred under a balloon of H2 for 5½ h. The reaction mixture was filtered through a plug of Celite and the filtrate was concentrated in vacuo to afford 4-methyl-6-(trifluoromethyl)pyridin-3-amine. LCMS calc.=177.1; found=177.1 (M+1)+. 1H NMR (600 MHz, CDCl3): δ 8.04 (s, 1H); 7.27 (s, 1H); 4.28 (s, 2H); 2.15 (s, 3H).
