Reaction Steps

Preparation of N-(4-methylthiazol-2-yl-3-phenoxy-5-(1-(pyridin-2-yl)ethylthio)pyridin-2-amine dihydrochloride: Following the procedure in Example 16, methyl 3-(6-(4-methylthiazol-2-ylamino)-5-phenoxypyridin-3-ylthio)propanoate (0.325 g, 0.809 mmol), 1M potassium 2-methylpropan-2-olate (2.83 mL, 2.83 mmol), and 2-(1-bromoethyl)pyridine (0.151 g, 0.809 mmol) were reacted to provide N-(4-methylthiazol-2-yl)-3-phenoxy-5-(1-(pyridin-2-yl)ethylthio)pyridin-2-amine hydrochloride (0.114 g, 30.8%) after reverse phase purification and HCl salt formation. 1H NMR (d6-DMSO) δ 8.58 (d, 1H), 8.09 (m, 1H), 8.04 (d, 1H), 7.58 (d, 2H), 7.45 (t, 2H), 7.23 (t, 1H), 7.02 (d, 2H), 6.95 (d, 1H), 6.79 (s, 1H), 4.67 (q, 1H), 2.28 (s, 3H), 1.62 (d, 3H); Mass spectrum (esi) m/z=421.1 (M+H-2HCl).
