Reaction Steps

Preparation of 4-(3-methoxyphenylthio)-N-4-methylthiazol-2-yl)pyridin-2-amine: Using the method of Example 3, Step B, 4-methylthiazol-2-amine (10.8 mL, 4.32 mmol), 2-chloro-4-(3-methoxyphenylthio)pyridine (0.989 g, 3.93 mmol), potassium phosphate (0.917 g, 4.32 mmol), Pd2(dba)3 (0.0899 g, 0.0982 mmol), and 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (0.0625 g, 0.108 mmol) were reacted to provide 4-(3-methoxyphenylthio)-N-(4-methylthiazol-2-yl)pyridin-2-amine (0.798 g, 61.7% yield). 1H NMR (d6-DMSO) δ 11.08 (s, 1H), 8.09 (d, 1H), 7.45 (t, 1H), 7.14 (m, 2H), 7.11 (m, 1H), 6.77 (s, 1H), 6.61 (dd, 1H), 6.52 (s, 1H), 3.80 (s, 3H), 2.20 (s, 3H); Mass spectrum (apci) m/z=330.2 (M+H).
