Reaction Steps

In a solution of 0.20 g of N-(5-bromo-2-pyrimidinyl)-4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazole-3-yl]-2-methyl benzoic acid amide synthesized in Step 1 of Synthetic Example 13 in 3 mL of N,N-dimethylacetamide, 0.082 g of zinc cyanide, 0.011 g of zinc, 0.013 g of tris(dibenzylideneacetone)dipalladium and 0.015 g of 1,1′-bis(diphenylphosphino)ferrocene were added, and stirred under nitrogen atmosphere at 100° C. for 2 hours. After the completion of the reaction, the reaction mixture was left and cooled to room temperature, and 20 mL of concentrated ammonia water and 20 mL of water were added, and extracted with ethyl acetate (20 mL×2). The organic phases were washed with water, and dehydrated with and dried over saturated sodium chloride aqueous solution and anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified with silica gel column chromatography that was eluated with ethyl acetate-hexane (1:1) to obtain 0.15 g of the aimed product as white crystal.
