실험 절차

2-Isopropyl-5-nitro-pyridine (1.30 g, 7.82 mmol) was dissolved in methyl alcohol (20 mL), and Raney Ni (0.25 g) was added. The mixture was stirred under H2 (1 atm) at room temperature for 2 h. The catalyst was filtered off, and the filtrate was concentrated under vacuum to give 2-isopropyl-5-amino-pyridine (E-9) (0.55 g, 52%). 1H NMR (CDCl3) δ 8.05 (s, 1 H), 6.93-6.99 (m, 2 H), 3.47 (br s, 2 H), 2.92-3.02 (m, 1 H), 1.24-1.26 (m, 6 H). ESI-MS 137.2 m/z (MH+).
