Procedure

To a pressure tube was added 5-(3,4-difluoro-phenoxy)-isoindole-1,3-dione (680 mg), potassium carbonate (1 g), 3-pentanone (20 ml), and methyl bromoacetate (295 μL). The resulting mixture was heated to 105° C. for 17 h. The reaction was diluted with 20 ml water and extracted with ethyl acetate (2×). The organic layer was dried and concentrated. The mixture was purified through silica gel chromatography with 4:1 hexanes/ethyl acetate and 3:1 hexanes/ethyl acetate to give 657 mg of the title compound.): 1H NMR (200 MHz, DMSO) δ 7.95 (d, J=9.0 Hz, 1H), 7.64-7.41 (m, 4H), 7.15-7.08 (m, 1H), 4.44 (s, 2H), 3.70 (s, 3H).
