To a stirred solution of 2-(1-tert-butoxycarbonylindol-3-yl)propionitrile (4.00 g, 14.8 mmol) in DCM (10 mL) was added TFA (10 mL) with caution. After 1 hour, the reaction was diluted with DCM (40 mL), washed with water (2×40 mL) and brine, then dried (Na2SO4), and concentrated under reduced pressure to give 2-(1H-indol-3-yl)propionitrile (2.5 g, 99%) as a pale brown solid; 1H-NMR (CDCl3): δ 8.25 (1H, d), 7.69 (1H, s), 7.65 (1H, d), 7.45 (1H, app t), 7.37 (1H, app t), 4.12 (1H, q), 1.79 (3H, d).
