To a stirred solution of 8-bromo-3-(4-fluorobenzoyl)-1,2,3,6-tetrahydroazepino[4,5-b]indole-5-carboxylic acid ethyl ester (compound in Example 37A, 70 mg, 0.15 mmol), 3-methoxyphenylboronic acid (58 mg, 0.38 mmol), and (o-tolyl)3P (24 mg, 0.077 mmol) in toluene/EtOH (2:1, 3 mL) was added 0.55 mL of 1M NaHCO3 solution and Pd(OAc)2 (7 mg) at ambient temperature. The reaction mixture was heated at 80° C. under N2 for 1.5 hours and samples monitored by LC-MS. The solution was diluted with DCM (10 mL) and washed with brine. The aqueous phase was extracted with DCM (10 mL) twice. The combined organic phase was dried over Na2SO4 and concentrated. The crude product was purified by flash chromatograph on silica gel, eluting with EtOAc-hexane (0-30%) to yield the title compound (68 mg) as a light yellow solid; 1H-NMR (CDCl3): δ 10.76 (1H, s), 8.20 (1H, s), 7.78 (4H, m), 7.52 (2H, m), 7.42 (1H, d), 7.36 (3H, m), 7.04 (1H, m), 4.43 (4H, m), 4.05 (3H, s), 3.45 (2H, m), 1.39 (3H, t). MS (ESI): 485 (MH+).
