실험 절차

Powdered K2CO3 (1.305 g, 9.44 mmol) was added to a stirred suspension of tert-butyl 4-{[2-chloro-6-(4-morpholinyl)-5-nitro-4-pyrimidinyl]amino}-1-piperidinecarboxylate (U.S. Pat. Appl. Publ. No. 2009/0181963, the disclosure of which is incorporated herein by reference in its entirety) (1.047 g, 2.36 mmol) and 2-difluoromethyl-4-methoxy-1H-benzimidazole (Example 2) (608 mg, 3.07 mmol) in DMF (70 mL) at room temperature, and the mixture was stirred for 2.5 days. The reaction mixture was diluted with water, and the resulting precipitate was collected by filtration and dried. Recrystallization from CH2Cl2/MeOH gave tert-butyl 4-{[2-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-5-nitro-4-pyrimidinyl]amino}-1-piperidinecarboxylate (1.27 g, 89%): mp 229-231° C.; 1H NMR (CDCl3) δ 8.64 (d, J=7.7 Hz, 1H), 7.81 (dd, J=8.4, 0.6 Hz, 1H), 7.36 (t, JHF=53.5 Hz, 1H), 7.36 (t, J=8.2 Hz, 1H), 6.84 (d, J=7.7 Hz, 1H), 4.36 (m, 1H), 4.11 (m, 2H), 4.06 (s, 3H), 3.85 (t, J=4.9 Hz, 4H), 3.65 (t, J=4.6 Hz, 4H), 3.01 (t, J=11.5 Hz, 2H), 2.08 (m, 2H), 1.64-1.51 (m, 2H), 1.48 (s, 9H); Anal. Calcd. for C27H34F2N8O6: C, 53.6; H, 5.7; N, 18.5. Found: C, 53.35; H, 5.7; N, 18.8%.
