To a solution of compound N-{1-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-3-azetidinyl}methanesulfonamide (Example 30) (182 mg, 0.36 mmol) in DMF (4 mL) was added dry powdered K2CO3 (1.0 g, 7.3 mmol) and iodomethane (0.5 mL, excess). The reaction mixture was stirred at 20° C. for 20 hrs and diluted with water. The resulting precipitate was collected by filtration, washed with water, and dried. Recrystallization from CH2Cl2/MeOH gave N-{1-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-3-azetidinyl}-N-methylmethanesulfonamide in 83% yield: mp (CH2Cl2/MeOH) 290-291; 1H NMR (DMSO-d6) δ7.99 (d, J=7.8 Hz, 1H), 7.75 (t, JHF=53.0 Hz, 1H), 7.40 (t, J=8.2 Hz, 1H), 6.95 (d, J=7.7 Hz, 1H), 4.78-4.71 (m, 1H), 4.46-4.26 (m, 4H), 3.98 (s, 3H), 3.80-3.79 (m, 4H), 3.69 (m, 4H), 2.93 (s, 3H), 2.91 (s, 3H); Anal. Calcd. for C21H26F2N8O4S: C, 48.1; H, 5.0; N, 21.4. Found: C, 47.9; H, 4.9; N, 21.5%.
