A mixture of the above amine (1.35 g, 6 mmol) and 1-[4-chloro-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-2-(difluoromethyl)-1H-benzimidazole (International Publ. No. WO 2002/088112, the disclosure of which is incorporated herein by reference in its entirety) (1.83 g, 5 mmol) and Et3N (1.4 mL, 10 mmol) in 50 mL THF was stirred at room temperature for 5 hrs and then diluted with water. The white solid was collected and dried. Chromatography on alumina, eluting with CH2Cl2 gave 1.42 g (43% yield) of N-[2-({4-[4-[2-(difluoromethyl)-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 (br dd, J=7.1, 1.2 Hz, 1H), 7.89 (br dd, J=6.8, 1.2 Hz, 1H), 7.53 (t, JHF=53.5 Hz, 1H), 7.46-7.38 (m, 2H), 4.00 (m, 4H), 3.89 (m, 4H), 3.79 (m, 4H), 3.40 (m, 4H), 3.21 (dd, J=8.1, 6.4 Hz, 2H), 2.78 (dd, J=8.1, 6.4 Hz, 2H), 2.27 (s, 6H).
