1h-Indole-3-acetonitrile, 6-nitro- → 2-(6-Amino-1h-indol-3-yl)acetonitrile

Participants

Reaction Steps

A mixture of (6-nitro-1H-indol-3-yl)-acetonitrile (B-9-a) (1.5 g, 74.5 mml) and 10% Pd—C (300 mg) in EtOH (50 mL) was stirred at room temperature under H2 (1 atm) for 5 h. Pd—C was removed via filtration and the filtrate was evaporated to give (6-amino-1H-indol-3-yl)-acetonitrile (B-9) (1.1 g, 90%). 1H NMR (DMSO-d6) δ 10.4 (br s, 1 H), 7.18 (d,J=8.4 Hz, 1 H), 6.94 (s, 1H), 6.52 (s, 1 H), 6.42 (dd,J=8.4, 1.8 Hz, 1 H), 4.76 (s, 2 H), 3.88 (s, 2 H); ESI-MS 172.1 m/z (MH+).
