Reaktionsschritte
4-Trifluoromethanesulfonyloxy-7-trifluoromethyl-quinoline-3-carboxylic acid ethyl ester (417 mg, 1 mmol), 2-cyanophenylboronic acid (162 mg, 1.1 mmol), tetrakis(triphenylphosphine)palladium(0) (58 mg) and potassium phosphate (318 mg, 1.5 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, concentrated, and the residue purified by flash column eluted with 30% ethyl acetate in hexane to yield 4-(3-cyano-phenyl)-7-trifluoromethyl-quinoline-3-carboxylic acid ethyl ester as a white solid.
