Vorschrift

A mixture of 2-(difluoromethyl)-4-methoxy-1-{4-(4-morpholinyl)-6-[4-(vinylsulfonyl)-1-piperazinyl]-1,3,5-triazin-2-yl}-1H-benzimidazole (Example 3) (0.536 g, 1 mmol) and 40% aqueous dimethylamine (10 mL) in THF (200 mL) was warmed gently until a clear solution was obtained. After 15 min, the THF was removed under vacuum and the residue was diluted with water to give N-[2-({4-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-1-piperazinyl}sulfonyl)ethyl]-N,N-dimethylamine: 1H NMR (CDCl3) δ 7.86 (dd, J=8.4, 0.6 Hz, 1H), 7.45 (t, JHF=53.5 Hz, 1H), 7.36 (t, J=8.2 Hz, 1H), 6.82 (d, J=7.8 Hz, 1H), 4.05 (s, 3H), 4.00 (m, 4H), 3.89 (m, 4H), 3.79 (m, 4H), 3.39 (m, 4H), 3.11 (dd, J=8.1, 6.4 Hz, 2H), 2.78 (dd, J=8.1, 6.4 Hz, 2H), 2.26 (s, 6H).
