Procedure

A mixture of 2-(difluoromethyl)-4-methoxy-1-{4-(4-morpholinyl)-6-[4-(vinylsulfonyl)-1-piperazinyl]-1,3,5-triazin-2-yl}-1H-benzimidazole (Example 3) (150 mg, 0.280 mmol) and N,N-diethylamine (0.14 mL, 1.35 mmol) in THF (20 mL) was stirred at room temperature for 17 hrs, refluxed for 1 hr, and then stirred at room temperature for 4 hrs. 1,4-Dioxane (20 mL) was added and the mixture was refluxed for 21 hrs. Additional N,N-diethylamine (0.14 mL, 1.35 mmol) was then added and the mixture was refluxed for another 4.5 hrs. The reaction mixture was cooled to room temperature and the solvents were removed under vacuum. The residue was diluted with water and extracted with CH2Cl2 (2×). The organic layers were combined, dried (Na2SO4), and concentrated under vacuum. Chromatography on silica, eluting with CH2Cl2/MeOH (100:0 to 98:2), gave N-[2-({4-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-1-piperazinyl}sulfonyl)ethyl]-N,N-diethylamine (54 mg, 53%).
