实验过程

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer, condenser and nitrogen inlet was purged with nitrogen and charged with 4,5,6,7-tetrahydro-1H-indole (3.00 g, 24.8 mmol), trichloroacetyl chloride (13.5 g, 74.4 mmol) and 1,2-dichloroethane (50 mL). The solution was stirred at 85° C. for 2 h. After that time, the reaction mixture was concentrated under reduced pressure to afford a 100% yield (6.50 g) of 2,2,2-trichloro-1-(4,5,6,7-tetrahydro-1H-indol-2-yl)ethanone 1 as a black semi-solid: 1H NMR (500 MHz, DMSO-d6) δ 11.94 (s, 1H), 7.05 (s, 1H), 2.62 (t, 2H, J=6.0 Hz), 2.47 (t, 2H, J=6.0 Hz), 1.80 (m, 2H), 1.65 (m, 2H); MS (ESI+) m/z 266.0 (M+H)
