Participants

Reaction Steps

In a manner similar to that described for Compound 12, the tricyclic bromide (129 mg, 0.49 mmol) and 5-chloro-2-methoxy-phenylboronic acid (100 mg, 0.54 mmol) were coupled to yield 2-(5-chloro-2-methoxy-phenyl)-3,4,5,6-tetrahydro-azepino[5,4,3-cd]indol-6-one, 100 mg (63%) as an off-white solid: m.p. 160-162° C.; 1H NMR (300 MHz, d6-DMSO) δ 2.81 (m, 2H), 3.34 (m, 2H), 3.84 (s, 3H), 7.20 (m, 2H), 7.46 (m, 2H), 7.55 (d, J=7.8 Hz, 1H), 7.68 (d, J=7.5 Hz, 1H), 8.05 (br t, 1H), 11.37 (br s, 1H). MS (FAB, MH+): 327. Anal. (C18H15ClN2O2) C, H, N, Cl.
