Procedure

A mixture of 4-[2-(5,8-difluoroquinazolin-4-ylamino)-ethyl]-2-methylphenol (0.47 g, 1.5 mmol), 2-fluoro-4-trifluoromethylpyridine (0.371 g, 2.25 mmol), and potassium carbonate (0.31 g, 2.25 mmol) in DMSO (7 mL) was heated at 90° C. overnight. The reaction was complete, as determined by LC-MS. After cooling to room temperature, water was added and the mixture was stirred for 10 min. The solid precipitate was collected by filtration, washed with water, and dried under vacuum at 50° C. to provide 0.533 g (77%) of (5,8-difluoroquinazolin-4-yl)-{2-[3-methyl-4-(4-trifluoromethylpyridin-2-yloxy)-phenyl]-ethyl}-amine as an off-white solid, M.P. 108-110° C. 1H NMR (CDCl3): δ 8.69 (s, 1H), 8.31 (d, J=5.1 Hz, 1H), 7.34 (m, 1H), 7.13-7.21 (m, 4H), 6.96-7.03 (m, 2H), 6.71-6.84 (br, 1H), 3.94 (m, 2H), 3.02 (t, J=6.9 Hz, 2H), 2.17 (s, 3H). LC/MS: 461.13 (M++1).
