In a manner similar to that described for Example YY, 3-(2-bromo-phenyl)-propionic acid methyl ester (243 mg, 1.00 mmol), diboron pinacol ester (279 mg, 1.10 mmol), 1,1′-bis(diphenyl phosphino)ferrocene dichloropalladium (24 mg, 0.03 mmol), and potassium acetate (294 mg, 3.00 mmol), 2-Bromo-3,4,5,6-tetrahydro-azepino[5,4,3-cd]indol-6-one (239 mg, 0.90 mmol), a second portion of 1,1′-bis(diphenylphosphino)ferrocene dichloropalladium (24 mg, 0.03 mmol), and sodium carbonate (2.5 mL of a 2.0 M aqueous solution, 5.00 mmol) were reacted to yield 3-[2-(6-oxo-3,4,5,6-tetrahydro-1H-azepino[5,4,3-cd]indol-2-yl)-phenyl]-propionic acid methyl ester, 92 mg (29%) as a beige solid: m.p. 201-201.5° C.; 1H NMR (300 MHz, d6-DMSO) δ 2.43 (t, J=7.5 Hz, 2H), 2.68 (m, 2H), 2.86 (t, J=8.1 Hz, 2H) 3.38 (m, 2H), 3.47 (s, 3H), 7.20 (t, J=7.8 Hz, 1H), 7.37 (m, 4H), 7.52 (dd, J=7.8, 0.6 Hz, 1H), 7.70 (dd, J=7.5, 0.6 Hz, 1H), 8.04 (br t, 1H), 11.41 (br s, 1H). MS (FAB, MH+): 349. Anal. (C21H20N2O3.0.3 CHCl3) C, H, N.
