Procedure

In a manner similar to that described for Compound 12, the tricyclic bromide (300 mg, 1.13 mmol) and 2-methoxyphenylboronic acid (189 mg, 1.24 mmol) were coupled to yield 2-(2-methoxy-phenyl)-1,3,4,5-tetrahydro-azepino[5,4,3-cd]indol-6-one, 177 mg (53%) as a brown solid: m.p. 254-255° C.; 1H NMR (300 MHz, d6-DMSO) DMSO) δ 2.81 (m, 2H), 3.36 (m, 2H), 3.83 (s, 3H), 7.08 (app t, J=7.5 Hz, 1H), 7.17 (m, 2H), 7.43 (m, 2H), 7.54 (dd, J=7.8, 0.6 Hz, 1H), 7.67 (dd, J=7.5, 0.6 Hz, 1H), 8.03 (br t, 1H), 11.27 (br s, 1H).
