To a solution ethyl {4-[4-(ethyloxy)-9-hydroxy-1,3-dioxo-1,3-dihydro-2H-benzo[f]isoindol-2-yl]-3-fluorophenyl}acetate (0.2 g, 0.458 mmol) in DMF (3 ml), was added sodium carbonate (0.097 g, 0.915 mmol) followed by 2,2,2-trifluoroethyl trifluoromethanesulfonate (0.159 g, 0.687 mmol). This was stirred at room temperature for 24 hours. Water was added to the reaction mixture with rapid stirring. The resulting yellow coloured solid was collected by filtration, washed with water and dried in the vacuum oven to give the title compound (0.119 g, 0.23 mmol). LC/MS: Rt=3.82, [MH]+ 520.
