実験手順

The above carbamate was hydrogenated over 5% Pd on carbon in MeOH. After removal of the solvent, the residue was combined with 0.19 g (0.48 mmol) 1-[4-chloro-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-2-(difluoromethyl)-4-methoxy-1H-benzimidazole (Example 2) and DIPEA in THF. The mixture was heated under reflux for 30 min and the solvent was removed. After dilution with water, the resulting solid was collected and dried. Chromatography on silica, eluting with CH2Cl2/EtOAc (93:7), gave 0.227 g (86% yield) of 1-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-N,N-dimethyl-4-piperidinesulfonamide: mp (MeOH) 260-264° C.; 1H NMR (CDCl3) δ 7.88 (dd, J=8.4, 0.6 Hz, 1H), 7.46 (t, JHF=53.5 Hz, 1H), 7.35 (t, J=7.7 Hz, 1H), 6.81 (d, J=7.7 Hz, 1H), 4.91 (br d, J=13.5 Hz, 2H), 4.05 (s, 3H), 3.88 (m, 4H), 3.78 (m, 4H), 3.27 (tt, J=11.8, 3.8 Hz, 1H), 2.95 (s, 6H), 2.17 (dd, J=12.7, 2.2 Hz, 2H), 1.85 (dq, J=12.6, 4.2 Hz, 2H); Anal. Calcd. for C23H30F2N8O4S: C, 50.0; H, 5.5; N, 20.3. Found: C, 49.9; H, 5.5; N, 20.4%.
