Reaction Steps

Using the method of Example 3, Step B, 2-chloro-4-(4-methoxyphenoxy)pyridine (2.952 g, 12.53 mmol), 4-methylthiazol-2-amine (28.47 mL, 11.39 mmol), potassium phosphate (2.417 g, 11.39 mmol), Pd2(dba)3, (0.2607 g, 0.2847 mmol) and 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (0.1812 g, 0.3131 mmol) were reacted in toluene (30 mL) and water (8 mL) to provide 4-(4-methoxyphenoxy)-N-(4-methylthiazol-2-yl)pyridin-2-amine (1.726 g, 44.50% yield) as yellow solid. 1H NMR (CDCl3) δ 8.10 (d, 1H), 6.96 (m, 2H), 6.87 (m, 2H), 6.42 (dd, 1H), 6.26 (d, 1H), 6.18 (d, 1H), 3.80 (s, 3H), 2.15 (s, 3H); Mass spectrum (esi) m/z=314 (100) (+H).
