Procedure

Under argon gas atmosphere, a mixture of ethyl 5-bromoquinoline-3-carboxylate (113 mg), 2,4,6-trifluorophenylboric acid (106 mg), bis(tri-t-butylphosphine)palladium (41 mg), cesium fluoride (123 mg), silver oxide (112 mg), and DMF (2 mL) was heated under stirring in an oil bath at 100° C. for 15 hours. The reaction liquid was returned to room temperature, diluted with water, and then extracted with ethyl acetate. The organic layer was concentrated under reduced pressure, and the resulting residue was purified under silica gel column chromatography (hexane/ethyl acetate) to obtain ethyl 5-(2,4,6-trifluorophenyl)quinoline-3-carboxylate (60 mg).
