Reaction Steps

To a mixture of N-{1-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-4-piperidinyl}methanesulfonamide (Example 17) (1.95 g, 3.62 mmol) and K2CO3 (6 g, excess) in DMF (20 mL) was added 3-bromo-1-propanol (4 mL, excess). The reaction mixture was stirred at 20° C. for 7 days and diluted with water. The resulting sticky material was extracted into CH2Cl2 (4×30 mL) and dried (Na2SO4). Evaporation of the solvent and the chromatography of the residue on silica, eluting with a gradient of CH2Cl2 and EtOAc (0-20%) followed by CH2Cl2/MeOH (97:3) gave N-{1-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-4-piperidinyl}-N-(3-hydroxypropyl)methanesulfonamide (1.04 g, 49%): mp (CH2Cl2/MeOH) 219-221° C.; 1H NMR (DMSO-d6) δ7.89 (d, J=8.2 Hz, 1H), 7.69 (t, JHF=52.9 Hz, 1H), 7.41 (t, J=8.2 Hz, 1H), 6.95 (d, J=7.9 Hz, 1H), 4.73 (d, J=12.8 Hz, 1H), 4.82 (d, J=12.3 Hz, 1H), 4.44 (t, J=5.1 Hz, 1H), 3.97 (S, 3H), 3.92-3.83 (m, 1H), 3.80-3.79 (m, 4H), 3.69 (m, 4H), 3.40-3.32 (m, 2H), 3.14-2.96 (m, 4H), 3.96 (s, 3H), 1.87-1.80 (m, 2H), 1.74-1.64 (m, 4H); Anal Calcd. for C25H34F2N8O5S: C, 50.33; H, 5.74; N, 18.78. Found: C, 50.2; H, 5.9; N, 18.5%.
