実験手順

4-Trifluoromethanesulfonyloxy-7-trifluoromethyl-quinoline-3-carboxylic acid ethyl ester (208 mg, 0.5 mmol), 4-methyl-2-methoxylphenylboronic acid (92 mg, 0.55 mmol), tetrakis(triphenylphosphine)palladium(0) (29 mg) and potassium phosphate (159 mg, 0.75 mmol) were heated together in dioxane (5 mL) to 80° C. overnight. The reaction mixture was then diluted with ethyl acetate and washed with brine twice. The organic layer was dried over sodium sulfate and concentrated to yield a yellow oil which was purified by flash column eluted with 30% ethyl acetate in hexane, then recrystallization from ethyl ether to yield 4-(3-methoxy-5-methyl-phenyl)-7-trifluoromethyl-quinoline-3-carboxylic acid ethyl ester as a white powder.
