실험 절차

A solution of 3-(3-bromophenyl)-2-(2,4,6-trifluorobenzyl)-7-(trifluoromethyl)-2H-indazole (2.0 g, 4.1 mmol) and trimethylsilyl-acetylene-tributyltin in 30 mL of toluene was degassed. Palladium-tetrakis-triphenylphosphine (0.046 g, 0.4 mmol) was added and the mixture heated at reflux for 18 hours. The reaction mixture was concentrated in vacuo and purified by flash chromatography (silica 60, hexane-ethyl acetate, 9:1) to give the title compound (1.8 g) as a white solid.
