(2-tert-butyl-5-nitro-1H-indol-7-yl)methanol → (5-amino-2-tert-butyl-1H-indol-7-yl)methanol

Participants

Reaction Steps

A mixture of (2-tert-butyl-5-nitro-1H-indol-7-yl)methanol (4.0 g, 16 mmol) and Raney Nickel (400 mg) in CH3OH (100 mL) was stirred for 5 g at room temperature under H2. The catalyst was filtered off through a celite pad and the filtrate was evaporated under vacuum to give (5-amino-2-tert-butyl-1H-indol-7-yl)methanol (3.4 g, 80%). 1H NMR (CDCl3, 400 MHz) δ 8.53 (br s, 1H), 6.80 (d, J=2.0 Hz, 1H), 6.38 (d, J=1.6 Hz, 1H), 4.89 (s, 2H), 1.37 (s, 9H).
