실험 절차

To a solution of 2-tert-butyl-6-nitro-1H-indole (1.3 g, 6.0 mmol) in MeOH (10 mL) was added Raney Nickel (0.2 g). The mixture was hydrogenated under 1 atm of hydrogen at room temperature for 3 h. The reaction mixture was filtered and the filtrate was concentrated. The residue was washed with petroleum ether to give 2-tert-butyl-1H-indol-6-amine (1.0 g, 89%). 1H NMR (300 MHz, DMSO-d6) δ 10.19 (s, 1H), 6.99 (d, J=8.1 Hz, 1H), 6.46 (s, 1H), 6.25 (dd, J=1.8, 8.1 Hz, 1H), 5.79 (d, J=1.8 Hz, 1H), 4.52 (s, 2H), 1.24 (s, 9H); MS (ESI) m/e (M+H+) 189.1.
