Procedure

A mixture of tert-butyl 4-[4-[2-(difluoromethyl)-4-(3-hydroxypropoxy)-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-1-piperazinecarboxylate from the previous step and 0.34 g (3.3 mmol) of Et3N in 20 mL of THF was cooled to 0° C. and 0.32 g (2.8 mmol) of methanesulfonyl chloride was added dropwise. After 1 hr, 6 g of 40% aqueous Me2NH was added, and the resulting mixture was stirred at room temperature for 36 hrs. The THF was removed under vacuum and the residue was diluted with water and extracted into CH2Cl2. Drying and removal of the solvent gave tert-butyl 4-[4-{2-(difluoromethyl)-4-[3-(dimethylamino)propoxy]-1H-benzimidazol-1-yl}-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-1-piperazinecarboxylate as an oil: 1H NMR (CDCl3) δ 7.87 (dd, J=8.4. 0.6 Hz, 1H), 7.48 (t, JHF=53.5 Hz, 1H), 7.33 (t, J=8.2 Hz, 1H), 6.85 (d, J=7.8 Hz, 1H), 4.31 (t, J=6.7 Hz, 2H), 3.87 (m, 8H), 3.79 (m, 4H), 3.53 (m, 4H), 2.51 (t, J=7.2 Hz, 2H), 2.26 (s, 6H), 2.13 (pentet, J=7.0 Hz, 2H), 1.50 (s, 9H).
