180 °C

In a round bottom flask equipped with a condenser was placed N-phenylacetamide (1.0 g, 7.40 mmol), copper (I) chloride (0.146 g, 1.480 mmol), potassium carbonate (1.329 g, 9.62 mmol), 1-bromo-3-fluorobenzene (1.942 g, 11.10 mmol) and xylene (5 mL). The suspension was heated to 180° C. and refluxed for 66 h. The suspension was filtered; and the filtrate was concentrated. The dark brown residue was dissolved in ether; filtered; and the filtrate was concentrated. The dark brown residue was dissolved in ethanol (10.00 mL), treated with potassium hydroxide (1.909 g, 34.0 mmol) and refluxed for 2 h. The solution was poured into of water (80 mL) and extracted with DCM. The combined DCM extract was washed with water (6 X), dried over MgSO4 and concentrated to afford the title compound as a dark brown solid (0.669 g,). LCMS m/z=188.2 [M+H]+.
