Reaktionsschritte

To a solution of 6-bromo-2,3,4,9-tetrahydro-1H-carbazol-1-amine (50 mg, 0.19 mmol) in dichloromethane (1 mL) was added phenyl isocyanate (23 μL, 0.21 mmol). The mixture was stirred at room temperature 15 hours and the resulting precipitate collected by filtration to give a gray solid (62% yield). 1H-NMR (DMSO-d6): δ 11.01 (s, 1H), 7.60 (d, 1H), 7.45 (m, 2H), 7.33-7.23 (m, 4H), 7.17 (dd, 1H), 6.94 (m, 1H), 6.63 (d, 1H), 5.02 (m, 1H), 2.68 (m, 2H), 2.06 (m, 1H), 1.95-1.70 (m, 3H); MS m/z 384 (M−1).
