20 mg of 3-[(E)-2-(4-fluorophenyl)-vinyl]-4-methoxy-1H-indazole-5-carboxylic acid (1-benzyloxyethyl-cyclopropyl)-amide obtained by Example 814 was dissolved in 1 mL of dichloromethane, added with 6.4 μl of trimethylsilyliodide at 0° C. under nitrogen atmosphere, and stirred at this temperature for 2 hours. The reaction solution was added with methanol to stop the reaction, and the solvent was concentrated, followed by purification by LC-MS, to afford 1.7 mg of the title compound.
