Reaction Steps

Methanesulfonyl chloride (0.07 mL, 0.904 mmol) was added drop-wise to a mixture of the above amine (102 mg, 0.229 mmol) and powdered K2CO3 (253 mg, 1.83 mmol) in CH2Cl2 (5 mL) at 0° C. The reaction mixture was stirred at 0° C. for 5 min and allowed to warm to room temperature. After 5 hrs, additional K2CO3 (127 mg, 0.919 mmol) and methanesulfonyl chloride (0.04 mL, 0.517 mmol) were added and the mixture stirred at room temperature for another 16 hrs. Water was added and the layers were separated. The organic layer was dried (Na2SO4) and the solvent was removed under vacuum. Recrystallization from CH2Cl2/MeOH gave 2-(difluoromethyl)-4-methoxy-1-{4-[4-(methylsulfonyl)-1-piperazinyl]-6-tetrahydro-2H-pyran-4-yl-1,3,5-triazin-2-yl}-1H-benzimidazole (73 mg, 61%): mp (CH2Cl2/MeOH) 242-244° C.; 1H NMR (CDCl3) δ 8.00 (dd, J=8.4, 0.6 Hz, 1H), 7.55 (t, JHF=53.5, 1H), 7.40 (t, J=7.9 Hz, 1H), 6.86 (d, J=7.7 Hz, 1H), 4.14-4.09 (m, 6H), 4.06 (s, 3H), 3.56 (m, 2H), 3.37 (br s, 4H), 2.96 (m, 1H), 2.83 (s, 3H), 1.99 (ddd, J=12.1, 7.9, 4.0, 4H); Anal. Calcd. for C22H27F2N7O4S: C, 50.5; H, 5.2; N, 18.7. Found: C, 50.6; H, 5.4; N, 18.6%.
