Procedure

In a manner similar to that described for Compound 12, the tricyclic bromide (300 mg, 1.13 mmol) and 4-pyridylboronic acid (153 mg, 1.24 mmol) were coupled to yield 2-pyridin-4-yl-1,3,4,5-tetrahydro-azepino[5,4,3-cd]indol-6-one, 45 mg (15%) as a beige solid: m.p. 250° C. (dec); 1H NMR (300 MHz, d6-DMSO) δ 3.13 (m, 2H), 3.41 (m, 2H), 7.29 (app t, J=7.8 Hz, 1H), 7.63 (m, 3H), 7.72 (dd, J=7.2, 0.9 Hz, 1H), 8.14 (br t, 1H), 8.69 (d, J=6.0 Hz, 2H), 11.82 (br s, 1H). MS (FAB, MH+) 364. Anal. (C16H13N3O) C, H, N.
