Methyl 8-fluoro-4-(4-fluorophenyl)-7-methylquinoline-2-carboxylate 7-9 (991 mg, 3.16 mmol), Benzoyl peroxide (102 mg, 0.316 mmol), and NBS (591 mg, 3.32 mmol) were heated at reflux in CCl4 for 5 hours. The solvent was removed in vacuo and the residue purified by column chromatography on a silica gel column, eluting with EtOAc/hexane (0-50%) to afford Methyl 7-(bromomethyl)-8-fluoro-4-(4-fluorophenyl)quinoline-2-carboxylate 7-10 (1.05 g, 85% yield) as a white solid, LCMS shows the compound is 67% pure, LRMS m/z (M+H)+ 392.0 found, 392.1 required.
