A mixture of N-(4-(6-chloropyrimidin-4-yloxy)-3-fluorophenyl)acetamide (Compound B of Example 13, 281 mg, 1.00 mmol), 4-benzyloxyaniline (Aldrich, 398 mg, 2.00 mmol), and 2-methoxyethyl ether (2 mL) was heated at 160° C. for 45 min. The cooled mixture was treated with H2O (50 mL) and extracted with EtOAc (100 mL). The EtOAc extract was washed with brine (3×25 mL), dried (MgSO4) and concentrated in vacuo to give the title compound (200 mg, 22%) as a purple solid. 1H NMR (400 MHz, DMSO-d6) δ 10.19 (s, 1H), 9.43 (s, 1H), 8.23 (s, 1H), 7.72 (dd, 1H, J=12.5, 2.0 Hz), 7.44-7.42 (m, 4H), 7.38 (dd, 2H, J=8.0, 6.9 Hz), 7.33-7.23 (m, 3H), 6.98 (d, 2H, J=9.0 Hz), 6.07 (s, 1H), 5.07 (s, 2H), 2.05 (s, 3H); MS (ESI+) m/z 445.13 (M+H)+.
