Reaction Steps

A solution of 2-tert-butyl-5-nitro-1H-indole-7-carboxylate (2.0 g, 7.2 mmol) and Raney Nickel (200 mg) in CH3OH (50 mL) was stirred for 5 h at the room temperature under H2 atmosphere. The catalyst was filtered off through a celite pad and the filtrate was evaporated under vacuum to give methyl 5-amino-2-tert-butyl-1H-indole-7-carboxylate (1.2 g, 68%) 1H NMR (CDCl3, 400 MHz) δ9.34 (brs, 1H), 7.24 (d, J=1.6 Hz, 1H), 7.10 (s, 1H), 6.12 (d, J=1.6 Hz, 1H), 3.88 (s, 3H), 1.45 (s, 9H).
