A solution of 1-benzyl-5-bromo-3-nitro-1H-pyridin-2-one (1.0 g, 3.24 mmol), 4-dibenzofuran-4-yl-phenyl-boronic acid (932 mg, 3.24 mmol), K2CO3 (1.34 g, 3 equiv., 9.7 mmol) in toluene (15 mL), ethanol (10 mL) and water (5 mL) was treated with treated with Pd(PPh3)4 (125 mg). After heating to 80° C. overnight, the solution was cooled to room temperature and the resulting solids were filtered and washed with ether (2×6 mL) to give 1-benzyl-5-(4-dibenzofuran-4-yl-phenyl)-3-nitro-1H-pyridin-2-one as a yellow solid (1.53 g, 92%).
