Procedure

A solution of 224 mg (0.5 mmol) of 2-(difluoromethyl)-4-methoxy-1-[4-(4-morpholinyl)-6-(1-piperazinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole (Example 2) and 130 mg (1 mmol) of DIPEA in 10 mL of CH2Cl2 was treated with 150 mg (1 mmol) of dimethylsulfamoyl chloride and the mixture was stirred at room temperature overnight. Water was added, and the organic layer was separated and dried. Chromatography on silica, eluting with CH2Cl2/EtOAc (9:1), gave 217 mg (78% yield) of 4-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-N,N-dimethyl-1-piperazinesulfonamide: mp (MeOH) 286-288° C.; 1H NMR (CDCl3) δ 7.86 (dd, J=8.4, 0.7 Hz, 1H), 7.44 (t, J=53.5 Hz, 1H), 7.35 (t, J=8.2 Hz, 1H), 6.82 (d, J=7.7 Hz, 1H), 4.05 (s, 3H), 3.96 (m, 4H), 3.89 (m, 4H), 3.78 (m, 4H), 3.34 (m, 4H), 2.87 (s, 6H); Anal. Calcd. for C22H29F2N9O4S: C, 47.7; H, 5.3; N, 22.8. Found: C, 47.95; H, 5.3; N, 22.9%.
