Reaction Steps

Tris(dibenzylideneacetone)dipalladium (0) (0.05749 g, 0.06278 mmol), 5-bromo-4-(2,6-difluorophenoxy)-N-(4-methylthiazol-2-yl)pyridin-2-amine (Example 128; 1.0 g, 2.511 mmol), 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (0.07265 g, 0.1256 mmol), methyl-3-mercaptopropanoate (0.2920 ml, 2.637 mmol), N-ethyl-N-isopropylpropan-2-amine (0.8748 ml, 5.022 mmol) and dioxane (50 mL) were heated under argon at 80° C. overnight and then concentrated. The residue was purified by column chromatography to provide the desired product (0.375 g, 33.79% yield) as a yellow solid. 1H NMR (CDCl3) δ 10.97 (s, 1H), 8.37 (s, 1H), 7.26 (m, 1H), 7.03 (t, 2H), 6.26 (s, 1H), 6.03 (s, 1H), 3.67 (s, 3H), 3.12 (t, 2H), 2.62 (t, 2H), 2.06 (s, 3H).
