Procedure

A mixture of 2-(difluoromethyl)-4-methoxy-1-[4-(4-morpholinyl)-6-(1-piperazinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole (Example 2) (150 mg, 0.378 mmol), 4-[3-(1-piperazinylsulfonyl)propyl]morpholine dihydrochloride (WO 2006/046040) (172 mg, 0.491 mmol) and DIPEA (0.40 mL, 2.27 mmol) in THF was stirred at room temperature for 17 hrs. The solvent was removed under vacuum, and the residue was diluted with water and extracted with CH2Cl2. The CH2Cl2 was dried (Na2SO4) and removed under vacuum. Chromatography on silica, eluting with CH2Cl2/MeOH (98:2) followed by recrystallization from CH2Cl2/hexanes gave 2-(difluoromethyl)-4-methoxy-1-[4-(4-morpholinyl)-6-(4-{[3-(4-morpholinyl)propyl]sulfonyl}-1-piperazinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole (188 mg, 78%). Treatment with methanesulfonic acid in CH2Cl2/MeOH and recrystallization from MeOH/EtOAc gave 2-(difluoromethyl)-4-methoxy-1-[4-(4-morpholinyl)-6-(4-{[3-(4-morpholinyl)propyl]sulfonyl}-1-piperazinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole methanesulfonate: mp 216-218° C.; 1H NMR (DMSO-d6) δ9.50 (br s, 1H), 7.89 (d, J=8.2 Hz, 1H), 7.69 (t, JHF=52.9 Hz, 1H), 7.41 (t, J=8.2 Hz, 1H), 6.96 (d, J=7.8 Hz, 1H), 4.01-3.93 (m, 6H), 3.98 (s, 3H), 3.82 (m, 4H), 3.70 (br s, 4H), 3.63 (t, J=12.1 Hz, 2H), 3.45 (d, J=12.6 Hz, 2H), 3.32 (m, 4H), 3.21 (t, J=7.1 Hz, 4H), 3.09 (dd, J=21.2, 11.8 Hz, 2H), 2.30 (s, 3H), 2.09 (m, 2H); Anal. Calcd for C28H41F2N9O8S2: C, 45.8; H, 5.6; N, 17.2. Found: C, 45.7; H, 5.6; N, 17.2%.
