実験手順
To a solution of 1H-indole-6-carbonitrile (1.6 g, 11.25 mmol) in DCM (60 mL) was added NBS (2.0 g, 11.25 mmol) in portions over a period of 5 minutes. The resultant mixture was stirred for 1 h. The reaction mixture was quenched with saturated sodium thiosulfate solution (25 mL) and further diluted with DCM (60 mL). The organic layer was washed with water (2×25 mL) followed by brine solution and dried over anhydrous sodium sulfate, filtered and concentrated to afford 2.50 g (99%) of the title compound, 1H NMR (300 MHz, CDCl3): δ 7.43 (d, J=7.4 Hz, 1 H), 7.45 (s, 1 H), 7.67 (d, J=6.9 Hz, 1 H), 7.79 (s, 1 H), 8.67 (br. s., 1H).
