실험 절차

A solution of 3-fluoro-4-(3-nitropyridin-4-yloxy)benzenamine (158 mg, 0.63 mmol) in THF (3 mL) was treated with a solution of solution of 2-(4-fluorophenyl)acetyl isocyanate in toluene (Compound D of Example 11, 1.3 mmol) and stirred at room temperature for 2 h then at 50° C. for 5 min. The mixture was concentrated and the residue treated with DMF (15 mL) and SiO2 (150 mg) and the mixture concentrated to dryness under vacuum and applied to a SiO2 column. The column was eluted with 20-60% EtOAc/hexanes to give the product, which was further purified by trituration with isopropyl ether to give a pale yellow solid (120 mg, 25%). 1H NMR (DMSO-d6) δ 11.07 (s, 1H), 10.63 (s, 1H), 9.19 (s, 1H), 8.67 (d, 1H, J=5.6 Hz), 7.85 (d, 1H, J=11.7 Hz), 7.46-7.45 (m, 2H), 7.39-7.35 (m, 2H), 7.18 (dd, 2H, J=8.6, 8.6 Hz), 7.01 (d, 1H, J=6.1 Hz), 3.76 (s, 2H).
