300 mg of 3-vinyl-4-methoxy-1-trityl-1H-indazole-5-carbonitrile and 180 μl of 3-bromopyridine were dissolved in a mixed solvent of 1 mL triethylamine/5 mL acetonitrile, added with 40 mg of tri-p-tolylphosphine and 27 mg of palladium acetate (II), and heated at 110° C. for 24 hours. The reaction solution was added with silica gel, the solvent was evaporated, and the resultant residue was purified by column chromatography (hexane:ethyl acetate=7:3), to afford 120 mg of the title compound as a pale yellow oil.
