Procedure

A mixture of 0.301 g (3.16 mmol) of 3-hydroxypyridine and 0.132 g (3.30 mmol) of NaOH was stirred in water until a clear solution was obtained. The water was removed and the residue was combined with a mixture of 0.301 g (3.16 mmol) of 1-[4-chloro-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-2-(difluoromethyl)-1H-benzimidazole and 0.02 g (0.06 mmol) of tris[2-(2-methoxyethoxy)ethyl]amine (TDA-1) in dioxane (12 mL). The resulting mixture was heated under reflux for 2 hr before being cooled, and diluted with water. The resulting precipitate was collected by filtration, and recrystallized from methanol to give 0.160 g (50% yield) of 2-(difluoromethyl)-1-[4-(4-morpholinyl)-6-(3-pyridinyloxy)-1,3,5-triazin-2-yl]-1H-benzimidazole: mp 229-231° C.; 1H NMR (CDCl3) δ8.63-8.60 (m, 2H), 8.12 (dd, J=7.1, 1.4 Hz, 1H), 7.87 (dd, J=7.1, 1.4 Hz, 1H), 7.59 (ddd, J=8.3, 2.7, 1.4 Hz, 1H), 7.45 (ddd, J=8.2, 4.6, 0.3 Hz, 1H), 7.41-7.34 (m, 2H), 7.25 (t, JHF=53.6 Hz, 1H), 3.99-3.96 (m, 2H), 3.89-3.83 (m, 4H), 3.79-3.77 (m, 2H); Anal. Calcd. for C20H17F2N7O2 0.7H2O: C, 54.8; H, 4.2; N, 22.4. Found: C, 54.5; H, 4.0; N, 22.0%.
