Reaction Conditions

Reaction Steps

A mixture of methyl 4-(2,4,6-trifluorophenyl)quinoline-6-carboxylate 1-oxide (1.3 g) and phosphoryl chloride (10 mL) was heated under stirring in an oil bath at 100° C. for 2 hours. The reaction mixture was concentrated under reduced pressure, and the resulting residue was 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 methyl 2-chloro-4-(2,4,6-trifluorophenyl)quinoline-6-carboxylate (370 mg).
