Procedure

N-(6-Methyl-2,3,4,9-tetrahydro-1H-carbazol-1-yl)-N′-phenylurea was prepared from 6-methyl-2,3,4,9-tetrahydro-1H-carbazol-1-amine and phenyl isocyanate in a similar manner as described above to give a white solid (82% yield). 1H-NMR (DMSO-d6): δ 10.57 (s, 1H), 8.27 (s, 1H), 7.42-7.34 (m, 2H), 7.20 (m, 2H), 7.17-7.11 (m, 2H), 6.87 (m, 1H), 6.82 (m, 1H), 6.51 (d, 1H), 4.92 (m, 1H), 2.58 (m, 2H), 2.32 (s, 3H), 1.97 (m, 1H), 1.87-1.70 (m, 3H); MS m/z 318 (M−1).
