반응 단계
3-trifluoromethylphenylboronic acid (278 mg, 1.46 mmol), tris(dibenzylideneacetone)-dipalladium(0) (61 mg, 0.066 mmol), potassium fluoride (255 mg, 4.38 mmol) and tri-tert-butylphosphonium tetrafluoroborate (46 mg, 0.159 mmol) in a flask were thoroughly flushed with argon. 3-bromo-4-methylbenzoic acid methyl ester (304 mg, 1.32 mmol) was added as solution in dioxane (5 ml). the mixture was stirred at 70° C. for 3 h, filtered over silica and evaporated to dryness. The raw material was purified by silica gel chromatography with a hetane/ethyl acetate gradient to yield the title compound (323 mg).
