80 °C

To a solution of 2-hydroxy-3-nitropyridine (Aldrich, 3.0 mmol, 420 mg) in 1,4-dioxane (20 mL), were added 4-fluorophenyl boronic acid (Combi-block, 6.0 mmol, 840 mg), copper(I) acetate (Aldrich, 4.5 mmol, 815 mg) and pyridine (2 mL). The reaction was heated at 80° C. for 20 h. After cooling to room temperature, 30 mL of cold water was added. The solid formed was collected by filtration, washed with ammonium hydroxide and water, and dried under vacuum to give the desired product (610 mg, 87% yield) as a solid. MS(ESI+) m/z 235.30 (M+H)+.
