A mixture of 3-bromo-2-methylaniline (200 mg, 1.075 mmol) and 5-fluoroisobenzofuran-1,3-dione (179 mg, 1.075 mmol) in acetic acid (2 mL) was heated at 100° C. for 4.5 h. The mixture was concentrated and the residue was purified by column chromatography (eluting with a gradient from hexane to 60:40 hexane-EtOAc) to give 2-(3-bromo-2-methylphenyl)-5-fluoroisoindoline-1,3-dione as a white solid (235 mg, 59%). Mass spectrum m/z 334, 336 (M+H)+.
