実験手順

To a solution of 2-(1-methylcyclopropyl)-5-nitro-1H-indole (0.70 g, 3.2 mmol) in EtOH (20 mL) was added Raney Nickel (100 mg) under nitrogen atmosphere. The mixture was stirred under hydrogen atmosphere (1 atm) at room temperature overnight. The catalyst was filtered off through a celite pad and the filtrate was evaporated under vacuum. The residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate=5/1) to afford 2-(1-methyl-cyclopropyl)-1H-indol-5-ylamine (170 mg, 28%). 1H NMR (400 MHz, CDCl3) δ 7.65 (brs, 1H), 7.08 (d, J=8.4 Hz, 1H), 6.82 (s, 1H), 6.57 (d, J=8.4 Hz, 1H), 6.14 (s, 1H), 3.45 (brs, 2H), 1.47 (s, 3H), 0.82-0.78 (m, 2H), 0.68-0.63 (m, 2H).
