Following the method of Example 1, Step B, 4-isopropylthiazol-2-amine (10.55 mL, 4.219 mmol), methyl 3-(2-chloropyridin-4-yloxy)benzoate (1.224 g, 4.641 mmol), potassium phosphate (0.9850 g, 4.641 mmol), tris(dibenzylideneacetone)dipalladium (0). (0.09658 g, 0.1055 mmol), and 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (0.06713 g, 0.1160 mmol) were reacted in water (3 mL) and toluene (11 mL) to give the title compound (1.297 g, 81.55% yield) as yellow solid. 1H NMR (CDCl3) δ 8.19 (d, 1H), 7.93 (dt, 1H), 7.76 (m, 1H), 7.50 (t, 1H), 7.30 (m, 1H), 6.50 (m, 1H), 6.48 (dd, 1H), 6.33 (s, 1H), 3.92 (s, 3H), 2.87 (m, 1H), 1.22 (d, 6H).
