Procedure
In a manner similar to that described for Compound 12, the tricyclic bromide (300 mg, 1.13 mmol) and thiophene-2-boronic acid (159 mg, 1.24 mmol) were coupled to yield 2-thiophen-2-yl-1,3,4,5-tetrahydro-azepino[5,4,3-cd]indol-6-one, 171 mg (56%) as a beige solid: m.p. 220.5-222.5° C.; 1H NMR (300 MHz d6-DMSO) δ 3.08 (m, 2H), 3.48 (m, 2H), 7.23 (m, 2H), 7.52 (m, 2H), 7.69 (m, 2H), 8.05 (br t, 1H), 11.60 (br s, 1H). MS (electrospray, MH+) 269. Anal. (C15H12N2)S 0.8 H2O) C, H, N.
