Participants

Reaction Steps

N-(6-Bromo-2,3,4,9-tetrahydro-1H-carbazol-1-yl)-N′-(4-methoxyphenyl)urea was prepared from 6-bromo-2,3,4,9-tetrahydro-1H-carbazol-1-amine and 4-methoxyphenyl isocyanate in a similar manner as described above to give a gray solid (61% yield). 1H-NMR (DMSO-d6): δ 10.99 (s, 1H), 8.16 (s, 1H), 7.60 (d, 1H), 7.38-7.27 (m, 3H), 7.17 (dd, 1H), 6.87 (d, 2H), 6.52 (d, 1H), 5.01 (m, 1H), 3.73 (s, 3H), 2.67 (m, 2H), 2.04 (m, 1H), 1.94-1.76 (m, 3H); MS m/z 414 (M−1).
