Reaction Steps

Using the method of Example 3, Step B, 4-methylthiazol-2-amine (3.50 mL, 1.40 mmol), 2-chloro-4-(phenylthio)pyridine (0.342 g, 1.54 mmol), potassium phosphate (0.327 g, 1.54 mmol), tris(dibenzylideneacetone)dipalladium(0) (0.0321 g, 0.0350 mmol) and 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (0.0223 g, 0.0385 mmol) were reacted in toluene (4 mL) and water (1.5 mL) to afford 4-methyl-N-(4-(phenylthio)pyridin-2-yl)thiazol-2-amine (0.296 g, 69.8% yield) as off white solid. 1H NMR (CDCl3) δ 8.07 (d, 1H), 7.54 (m, 2H), 7.44 (m, 3H), 6.57 (dd, 1H), 6.45 (d, 1H), 6.32 (d, 1H), 2.24 (d, 3H); Mass spectrum (apci) m/z=300 (100) (M+H).
