Procedure
N-(6-Chloro-2,3,4,9-tetrahydro-1H-carbazol-1-yl)-N′-phenylurea was prepared from 6-chloro-2,3,4,9-tetrahydro-1H-carbazol-1-amine and phenyl isocyanate in a similar manner as described above to give a white solid (74% yield). 1H-NMR (DMSO-d6): δ 10.93 (s, 1H), 8.30 (s, 1H), 7.41-7.36 (m, 3H), 7.28 (d, 1H), 7.21 (m, 2H), 7.00 (dd, 1H), 6.88 (m, 1H), 6.57 (d, 1H), 4.95 (m, 1H), 2.59 (m, 2H), 1.98 (m, 1H), 1.88-1.70 (m, 3H); MS m/z 338 (M−1).
