A mixture of Example 215 (1.0 eq) in 1,2-dimethoxyethane (10 mL) and water (5 mL) was reacted with N-[2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1-methyl-1H-indole-2-carboxamide (1.2 eq), Na2CO3 (2.4 eq), and Pd(PPh3)4 (0.06 eq) at 95° C. for 18 hours. The organic solvent was removed in vacuo and the the mixture was extracted with dichloromethane. The extract was dried (MgSO4), filtered, and concentrated. The residue was purified by preparative reverse phase HPLC (Rainin C18, 8 mm, 300 Å, 25 cm; 40% acetonitrile/0.1M ammonium acetate isocratic for 5 minutes, then 40–100% acetonitrile/0.1M ammonium acetate over 30 minutes, 21 mL/min). The acetonitrile was removed in vacuo and the aqueous mixture was lyophilized to provide the desired product. 1H NMR (DMSO-d6, 400 MHz) δ 9.52 (s, 1H), 8.45 (s, 1H), 8.02 (t, 1H), 7.91 (s, 1H), 7.71 (d, 1H), 7.55–7.63 (m, 2H), 7.28–7.38 (m, 2H), 7.23 (s, 1H), 7.08–7.18 (m, 2H), 7.03 (d, 1H), 5.57–5.69 (br s, 2H), 4.04 (s, 3H), 3.93 (s, 3H), 3.92 (s, 3H); reverse phase HPLC (Delta Pak C18, 5 μm, 300 Å, 15 cm; 50%-100% acetonitrile/0.1M ammonium acetate over 10 min, 1 mL/min) Rt=9.30 min.; MS m/e 536 (M+H)+.
