(E)-2-[2-(1H-indazol-3-yl)vinyl]phenylamine (60 mg, 0.26 mmol) obtained in Example 2 was dissolved in THF (1.5 mL) and the solution was added with triethylamine (71 μL, mmol) and p-fluorobenzoylchloride (45 μL, 0.38 mmol), followed by stirring at room temperature for 30 minutes. Further, the reaction mixture was added with potassium carbonate and stirred for a while. Then, the solid precipitated by adding water to the mixture was collected by filtration and the solid was triturated in ethanol to obtain Compound 3 (57 mg, 62%).
