Reaction Steps

In a test tube for microwave reactor, a solution of 0.20 g of 4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazol-3-yl]-2-methyl benzoic acid amide synthesized in Step 1 of Synthetic Example 19, 0.10 g of 5-bromopyrimidine, 4.8 mg of copper iodide, 0.21 g of potassium phosphate and 4.4 mg of N,N-dimethyl ethylene diamine in 1 mL of 1,4-dioxane was placed, and reacted by use of a microwave focused chemical synthesizer (Discover manufactured by CEM Corporation) at 120 W and 120° C. for 20 minutes. After the completion of the reaction, insoluble material was removed through silica gel column, 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 0.13 g of the aimed product as white crystal.
