Benzoyl chloride → N-(6-bromo-2,3,4,9-tetrahydro-1H-carbazol-1-yl)benzamide

Participants

Reaction Steps

To a solution of 6-bromo-2,3,4,9-tetrahydro-1H-carbazol-1-amine (50 mg, 0.19 mmol) and benzoyl chloride (24 μL, 0.21 mmol) in dichloromethane (1 mL) at 0° C. was added diisopropylethylamine (66 μL, 0.38 mmol). The mixture was stirred at room temperature 15 hours, the solvent removed, and the residue purified by flash chromatography (0-30% ethyl acetate-hexanes) to give 18 mg (26% yield) of a yellow solid. 1H-NMR (CDCl3): δ 8.97 (s, 1H), 7.78 (d, 2H), 7.61 (m, 1H), 7.52 (m, 1H), 7.44 (t, 2H), 7.23 (m, 1H), 7.17 (d, 1H), 6.42 (d, 1H), 5.34 (m, 1H), 2.72 (m, 2H), 2.32 (m, 1H), 2.02-1.93 (m, 3H); MS m/z 369 (M−1).
