Reaction Steps

In a 3-necked 5 L flask, equipped with a mechanic stirrer, a condenser, and a J-Kem temperature probe, a solution of 5-fluoro-2-nitrotoluene (158 g, 1.02 mol) in N,N-dimethylacetamide (500 mL) was added to a mixture of 5-fluoro-2-hydroxybenzonitrile (147 g, 1.07 mol) and potassium carbonate (163 g, 1.2 mol) in N,N-dimethylacetamide (573 mL) at room temperature. The mixture was heated to 100° C. After 8 hours, the reaction mixture was cooled to room temperature and water (3400 mL) was added in an ice bath. The precipitate was filtered, washed with water (1073 mL×2), and dried in vacuum (40° C.) to give (264 g, 90%) of the desired compound as a brown solid. MS (APCI−) m/z 272 (M−1) was detected. 1H NMR (400 MHz, CDCl3) δ 8.10 (d, 1H, J=9 Hz), 7.41-7.48 (m, 1H), 7.38 (m, 1H), 7.07-7.14 (m, 1H), 6.88-7.10 (m, 1H), 2.63 (s, 3H).
