Cs2CO3 (1.745 g, 5.35 mmol) was added to a solution of Succinimide (0.292 g, 2.94 mmol) and methyl 7-(bromomethyl)-8-fluoro-4-(4-fluorophenyl)quinoline-2-carboxylate 7-10 (1.05 g, 2.68 mmol) in DMF (13.39 ml) and the reactant stirred at rt for 30 min. The reaction was quenched with KH2PO4 (saturated) and the mixture was extracted with ethyl acetate (×3). The combined organic fractions were dried (MgSO4), filtered and the solvent was evaporated under reduced pressure. The solvent was removed in vacuo and the residue purified by column chromatography on a silica gel column, eluting with EtOAc/hexane (0-100%) to afford Methyl 7-[(2,5-dioxopyrrolidin-1-yl)methyl]-8-fluoro-4-(4-fluorophenyl)quinoline-2-carboxylate 7-11 as a white solid, LCMS shows the compound is 90% pure, LRMS m/z (M+H)+ 411.2 found, 411.1 required.
