2-(4-Fluorophenyl)acetyl isocyanate (Compound D of Example 11, 0.362 M, 0.351 mL, 0.127 mmol, 1.3 eq) was added to a solution of 4-(4-amino-2-fluorophenoxy)pyridin-2-amine (0.022 g, 0.100 mmol, 1.0 eq) in CH2Cl2 (2.0 mL) at room temperature. The reaction mixture was stirred for 13 h at room temperature and then concentrated in vacuo. The residue was purified by silica gel flash chromatography (Merck gel 40-63 μM, 230-240 mesh, 1:1 ethyl acetate/hexane) to afford the title compound (0.025 g, 64%) as a solid. 1H NMR (CD3OD) δ 7.62-7.67 (m, 2H), 7.23-7.29 (m, 2H), 7.07-7.12 (m, 2H), 6.95-6.99 (m, 2H), 6.12-6.14 (m, 1H), 5.86-5.87 (m, 1H), 3.61 (s, 2H); MS (ESI+) m/z 399 (M+H)+; HRMS (ESI+) calcd.: 399.1269. found: 399.1269.
