الإجراء التجريبي

3.9 mg of 1H-pyrazole-3-carboxaldehyde was added to a dimethylformamide (0.5 ml) solution of 15 mg of 4-(2-fluoro-phenoxy)-5-(6-methanesulfonyl-pyridin-3-yloxy)-benzene-1,2-diamine obtained in Example 200, and the reaction liquid was stirred at 90° C. for 30 minutes. The solvent was evaporated away under reduced pressure, and the resulting residue was purified through partitioning thin-layer chromatography (Kieselgel™ 60F254, Art 5744 (by Merck), chloroform/methanol=9/1) to obtain the entitled compound as a white solid.
