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), N,N-dimethyl-3-(1-piperazinylsulfonyl)-1-propanamine dihydrochloride (WO 2006/046040) (151 mg, 0.491 mmol), and DIPEA (0.40 mL, 2.27 mmol) in DMSO was stirred at room temperature for 30 minutes. The reaction mixture was diluted with water; and the resulting precipitate was collected by filtration, washed with water, and dissolved in CH2Cl2. The solution was dried (Na2SO4) and the solvent removed under vacuum. Chromatography on silica eluting with CH2Cl2/MeOH (95:5), followed by additional chromatography on silica eluting with CH2Cl2/MeOH (96:4) gave N-[3-({4-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-1-piperazinyl}sulfonyl)propyl]-N,N-dimethylamine (91 mg, 40%). Treatment with 1.25 M HCl solution in MeOH and recrystallization from MeOH/EtOAc gave the hydrochloride salt: mp 209-211° C.; 1H NMR (DMSO-d6) δ 10.16 (br s, 1H), 7.89 (d, J=8.4 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), 3.98 (s, 3H), 3.94 (m, 4H), 3.82 (m, 4H), 3.70 (br s, 4H), 3.33 (m, 4H), 3.23 (dd, J=9.3, 5.8 Hz, 2H), 3.12 (m, 2H), 2.75 (s, 6H), 2.08 (td, J=15.4, 7.8 Hz, 2H); Anal. Calcd. for C25H36ClF2N9O4S.0.5H2O: C, 46.8; H, 5.8; N, 19.7. Found: C, 46.9; H, 5.8; N, 19.4%.
