Reaction Steps

Using the method of Example 3, Step B, 2-chloro-4-(3-methoxyphenoxy)pyridine (2.95 g, 12.5 mmol), 4-methylthiazol-2-amine (28.5 mL, 11.4 mmol), potassium phosphate (2.66 g, 12.5 mmol), Pd2(dba)3 (0.261 g, 0.285 mmol) and 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (0.181 g, 0.313 mmol) were reacted in toluene (30 mL) and water (8 mL) to provide 4-(3-methoxyphenoxy)-N-(4-methylthiazol-2-yl)pyridin-2-amine (3.44 g, 88.7% yield) as yellow solid. 1H NMR (CDCl3) δ 8.14 (d, 1H), 7.26 (t, 1H), 6.76 (m, 1H), 6.63 (m, 1H), 6.58 (t, 1H), 6.46 (dd, 1H), 6.27 (m, 2H), 3.75 (s, 3H), 2.17 (s, 3H); Mass spectrum (esi) m/z=314 (100) (M+H).
