Procedure

In a manner similar to that described for Compound 12, the tricyclic bromide (300 mg, 1.13 mmol) and 3-pyridylboronic acid (153 mg, 1.24 mmol) were coupled to yield 2-pyridin-3-yl-1,3,4,5-tetrahydro-azepino[5,4,3-cd]indol-6-one, 75 mg (25%) as a light brown solid: m.p. 260.5-262.0° C.; 1H NMR (300 MHz, d6-DMSO) δ 3.07 (m, 2H), 3.40 (m, 2H), 7.25 (app t, J=7.8 Hz, 1H), 7.57 (m, 2H), 7.71 (dd, J=7.5, 0.9 Hz, 1H), 8.05 (m, 1H), 8.12 (br t, 1H), 8.59 (m, 1H), 8.88 (m, 1H), 11.75 (br s, 1H). MS (FAB, MH+) 264. Anal. (C16H13N3O.0.2 H2O) C, H, N.
