Participants

Reaction Steps

DIPEA (0.78 mL, 4.48 mmol) was added to a mixture of 2-(difluoromethyl)-4-methoxy-1-[4-(4-morpholinyl)-6-(1-piperazinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole (Example 2) (200 mg, 0.449 mmol) and 3-pyridinesulfonyl chloride (159 mg, 0.859 mmol) at room temperature under nitrogen. The reaction mixture was stirred at room temperature for 18.5 hrs. Water was added and the phases were separated. The organic phase was dried (Na2SO4) and the solvent was removed under vacuum. Chromatography on silica, eluting with CH2Cl2/MeOH (99:1), gave 2-(difluoromethyl)-4-methoxy-1-{4-(4-morpholinyl)-6-[4-(3-pyridinylsulfonyl)-1-piperazinyl]-1,3,5-triazin-2-yl}-1H-benzimidazole (227 mg, 86%).
