Reaction Steps
To a suspension of 2-amino-5-bromo-3-nitropyridine (2.2 g, 10.1 mmol) in dimethoxyethane (20 mL) were added 4-fluorophenylboronic acid (4.83 g, 13.1 mmol), tetrakis(triphenylphosphine)palladium (580 mg, 0.50 mmol) and 2N aqueous sodium carbonate solution (10 mL). The mixture was stirred at 80° C. for 9 hours under a nitrogen atmosphere. After the reaction mixture was cooled to room temperature, it was diluted with ethyl acetate to give a precipitate, which was collected by filtration, washed with ethyl acetate and then dried to give the title compound (1.76 g, 76%).
