To a solution of methyl(5-{3-[(2-chloro-5-fluoro-4-pyrimidinyl)(methyl)amino]propoxy}-1H-indol-1-yl)acetate (Example 84, 0.1 g, 0.25 mmol) in toluene (3.75 mL), dioxane (0.75 mL), and water (0.88 mL) were added sodium carbonate (0.26 g, 2.46 mmol), 4-methoxyphenyl boronic acid (0.15 g, 0.98 mmol), and PdCl2(dppf)(CH2Cl2) (0.04 g, 0.05 mmol). The mixture was heated at 80° C. for 4 h and then concentrated under reduced pressure. The product (0.11 g, 94%) was obtained after column chromatography (67% hexanes in EtOAc). 1H NMR (300 MHz, CD2Cl2) δ 8.31 (d, 2H), 8.06 (d, 1H), 7.12-7.07 (m, 3H), 6.95-6.87 (m, 3H), 6.41 (d, 1H), 4.85 (s, 2H), 4.11 (t, 2H), 3.94 (t, 2H), 3.86 (s, 3H), 3.76 (s, 3H), 3.35 (d, 3H), 2.26-2.20 (m, 2H).
