실험 절차

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 concentrated. After dilution with water, the resulting solid was collected and dried. Chromatography on alumina, eluting with CH2Cl2/EtOAc (9:1), gave 0.127 g (39% yield) of 1-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-N-methyl-4-piperidinesulfonamide: mp (MeOH) 261-263° C.; 1H NMR (CDCl3) δ 7.87 (dd, J=8.4, 0.6 Hz, 1H), 7.46 (t, JHF=53.6 Hz, 1H), 7.35 (t, J=8.0 Hz, 1H), 6.82 (d, J=7.7 Hz, 1H), 4.93 (br d, J=13.5 Hz, 2H), 4.05 (s, 3H), 4.02 (q, J=5.3 Hz, 1H), 3.88 (m, 4H), 3.78 (m, 4H), 3.22 (tt, J=11.8, 3.7 Hz, 1H), 3.00 (m, 2H), 2.86 (d, J=5.3 Hz, 3H), 2.24 (br d, J=12.0 Hz, 2H), 1.85 (dq, J=12.5, 4.4 Hz, 2H); Anal. Calcd. for C22H28F2N8O4S: C, 49.1; H, 5.2; N, 20.8. Found: C, 49.2; H, 5.3; N, 21.0%.
