実験手順

To a solution of N-(4-((2-aminopyridin-4-yl)oxy)-2,5-difluorophenyl)-N′-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide (130 mg, 0.29 mmol) in 10 mL, of anhydrous tetrahydrofuran was added diisopropylethylamine (75 mg, 0.58 mmol). A solution of methoxyacetyl chloride (34.5 mg, 0.32 mmol) in THF (1 mL) was added drop wise at 0° C. The resultant reaction mixture was stirred at R.T. for 0.5 h. It was diluted with ethyl acetate, washed with brine, dried over sodium sulfate and concentrated. The residue was purified by prep-TLC to give N-(2,5-difluoro-4-((2-(2-methoxyacetamido)pyridin-4-yl)oxy)phenyl)-N′-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide (75 mg, 50% yield). 1H NMR (400 MHz, CDCl3): δ 9.79 (s, 1H), 8.89 (s, 1H), 8.53 (s, 1H), 8.30 (dd, J=12.0, 7.2 Hz, 1H), 8.17 (d, J=5.6 Hz, 1H), 7.83 (d, J=2.4 Hz, 1H), 7.49-7.45 (m, 2H), 7.07-6.99 (m, 3H), 6.64 (dd, J=5.6, 2.4 Hz 1H), 3.98 (s, 2H), 3.49 (s, 3H), 1.78-1.66 (m, 4H); MS (ESI): m/z 515.2 [M+H]+.
