Ethyl 3-iodobenzoate → Ethyl 3-({3-[2-(2,4,6-trifluorobenzyl)-7-(trifluoromethyl)-2H-indazol-3-YL]phenyl}ethynyl)benzoate

Participants

Reaction Steps

A solution of 3-(3-ethynylphenyl)-2-(2,4,6-trifluorobenzyl)-7-(trifluoromethyl)-2H-indazole (0.103 g, 0.24 mmol), ethyl 3-iodobenzoate (0.042 mL, 0.25 mmol), tetrabutylammonium acetate (0.108 g, 0.36 mmol) and 8.8 mg of tris-(dibenzylidineacetone)-dipalladium in 2 mL of dry DMF was stirred at ambient temperature for 3 hours. The reaction mixture was partitioned with ethyl acetate and H2O. The organic phase was concentrated in vacuo and purified by flash chromatography (silica 60, CH2Cl2-hexane, 1:1) to give the title compound (0.065 g).
