Reaction Steps

Using the method of Example 3, Step B, 4-methylthiazol-2-amine (0.600 g, 5.26 mmol), ethyl 4-fluoro-3-(2-chloropyridin-4-yloxy)benzoate (1.55 g, 5.26 mmol), potassium phosphate (1.23 g, 5.78 mmol), Pd2(dba)3 (0.120 g, 0.131 mmol), and 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (0.084 g, 0.131 mmol) were reacted to provide ethyl 4-fluoro-3-(2-(4-methylthiazol-2-ylamino)pyridin-4-yloxy)benzoate (1.60 g, 77% yield). 1H NMR (CDCl3) δ 10.16 (bs, 1H), 8.20 (d, 1H), 7.97 (m, 1H), 7.86 (dd, 1H), 7.26 (t, 1H), 6.48 (dd, 1H), 6.29 (d, 1H), 6.28 (d, 1H), 4.38 (q, 2H), 2.18 (s, 3H), 1.38 (t, 3H); Mass spectrum (esi) m/z 374 (100) (M+H).
