2-fluoro-6-hydroxybenzonitrile (411 mg, 3 mmol), 2-(3-bromopropyl)isoindoline-1,3-dione (885 mg, 3.3 mmol), and potassium carbonate (1.24 g, 9 mmol) were heated overnight at 70° C. in N,N-dimethylformamide (6 mL). The mixture was cooled, diluted with water, and the precipitate filtered and dried to give 922 mg of the title compound as a white solid. 1H NMR (DMSO-d6) δ 7.79-7.87 (m, 4H), 7.69 (td, J=8.6, 6.9 Hz, 1H), 7.01-7.07 (m, 2H), 4.22 (t, J=5.8 Hz, 2H), 3.79 (t, J=6.6 Hz, 2H), 2.11 (quin, J=6.1 Hz, 2H).
