Reaction Steps

Under an atmosphere of protective gas, 0.1 g of 3-chloro-5-(3,3-dichloroprop-2-enyloxy)-1-iodo-2-[3-(5-trifluoromethylpyrid-2-yloxy)propyloxy]benzene, 0.03 g of 1-chloro-2-ethynylbenzene and 0.003 g of copper(I) iodide were dissolved in 1 ml of triethylamine. 0.005 g of bis(triphenylphosphine)palladium(II) chloride was added, and the mixture was stirred at 70° C. for 1 hour. The mixture was then allowed to cool and concentrated under reduced pressure, and the resulting residue was subjected to chromatographic purification. Yield: 0.085 g (84%)
