Procedure
In a manner similar to that described for Compound 12, the tricyclic bromide (300 mg, 1.13 mmol) and thiophene-3-boronic acid (159 mg, 1.24 mmol) were coupled to yield 2-thiophen-3-yl-1,3,4,5-tetrahydro-azepino[5,4,3-cd]indol-6-one, 249 mg (82%) as a beige solid: m.p. 255-256° C.; 1H NMR (300 MHz, d6-DMSO) δ 3.08 (m, 2H), 3.43 (m, 2H), 7.19 (t, J=7.8 Hz, 1H), 7.54 (m, 2H), 7.67 (dd, J=7.5, 0.9 Hz, 1H), 7.74 (m, 1H), 7.78 (m, 1H), 8.03 (br t, 1H), 11.49 (br s, 1H). MS (electrospray, MH+) 269. Anal. (C15H12N2OS.0.35 H2O) C, H, N, S.
