실험 절차

In 10 ml of a solution of 1-trifluoromethylethenyl zinc bromide prepared according to the method described in documents in 1M tetrahydrofuran, 1.0 g of 3-bromodifluoromethoxy-1-iodobenzene and 0.05 g of dichlorobis(triphenylphosphine) palladium (II) were added, and stirred under reflux with heat for 2 hours. After the completion of the reaction, the reaction mixture was poured in 20 ml of diluted hydrochloric acid, extracted with ethyl acetate (50 ml×1). The organic phase was dehydrated with saturated sodium chloride aqueous solution and dried over anhydrous sodium sulfate, and then the solvent was distilled off under reduced pressure. The residue was dissolved in hexane, and high polar impurities were excluded by treating with silica gel to obtain 0.77 g of crude aimed product as colorless oily substance. The resulting product was used as such without purification for the next step.
