Procedure
To a mixture of 2-(difluoromethyl)-4-methoxy-1-[4-(4-morpholinyl)-6-(4-piperidinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole (Example 13) (0.891 mg, 2 mmol) and DIPEA (0.77 g, 6 mmol) in CH2Cl2 (100 mL) was added dropwise 2-chloroethanesulfonyl chloride (0.49 g, 3 mmol) at 0° C. After addition, the reaction mixture was stirred at 0° C. for additional 2 hrs. The reaction mixture was quenched with water (100 mL). The organic layer was washed successively with aqueous HOAc (1%, 100 mL) and aqueous NH3, and dried. Chromatography on silica eluting with CH2Cl2/EtOAc (9:1) gave 0.589 g (55% yield) of 2-(difluoromethyl)-4-methoxy-1-{4-(4-morpholinyl)-6-[1-(vinylsulfonyl)-4-piperidinyl]-1,3,5-triazin-2-yl}-1H-benzimidazole: mp (MeOH) 229-232° C.; 1H NMR (CDCl3) δ 7.99 (dd, J=8.4, 0.7 Hz, 1H), 7.54 (t, JHF=53.6 Hz, 1H), 7.39 (t, J=8.3 Hz, 1H), 6.85 (d, J=7.6 Hz, 1H), 6.47 (dd, J=16.6, 9.9 Hz, 1H), 6.27 (d, J=16.6 Hz, 1H), 6.05 (d, J=9.9 Hz, 1H), 4.06 (s, 3H), 4.00-3.97 (m, 4H), 3.89-3.79 (m, 6H), 2.78 (m, 3H), 2.17 (br dd, J=13.6, 3.0 Hz, 2H), 2.01 (ddd, J=25.2, 11.7, 4.1 Hz, 2H); Anal. Calcd. for C23H27F2N7O4S: C, 51.6; H, 5.1; N, 18.3. Found: C, 51.7; H, 5.2; N, 18.25%.
