Procedure

DIPEA (0.29 mL, 1.66 mmol) was added to a suspension of 2-(difluoromethyl)-4-methoxy-1-[4-(4-morpholinyl)-6-(1-piperazinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole (Example 2) (150 mg, 0.336 mmol) and 4-[2-(chlorosulfonyl)ethyl]pyridinium chloride (122 mg, 0.504 mmol) in CH2Cl2 (10 mL) at room temperature under nitrogen, and the mixture was stirred for 3 hrs. Additional 4-[2-(chlorosulfonyl)ethyl]pyridinium chloride (41 mg, 0.169 mmol) was added and the mixture stirred for another 21 hrs. Water was added and the phases were separated. The aqueous phase was extracted with CH2Cl2 (1×), the combined organic extracts were dried (Na2SO4), and the solvent was removed under vacuum. Chromatography on silica eluting with CH2Cl2/MeOH (100:0 to 98:2) followed by recrystallization from CH2Cl2/MeOH gave 2-(difluoromethyl)-4-methoxy-1-[4-(4-morpholinyl)-6-(4-{[2-(4-pyridinyl)ethyl]sulfonyl}-1-piperazinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole (134 mg, 65%).
