To a solution of N-(3-aminophenyl)-2-(3-nitrophenyl)acetamide-hydrogen chloride (0.11 g, 0.35 mmol) and 2,4,5-trichloropyrimidine (0.065 g, 0.35 mmol) in DMF (1 mL) was added potassium carbonate (0.20 g, 1.4 mmol). The resulting mixture was stirred overnight at room temperature. Additional triethylamine (0.099 mL, 0.71 mmol) was then added an stirred overnight again. The reaction was quenched with sat'd NH4Cl and water. EtOAc was added and the layers separated. The aqueous was extracted with EtOAc. The combined organics were washed with water and brine then dried (MgSO4), filtered, and concentrated. The resulted mixture was purified by column chromatography to give the desired product (0.080 g, 53%).
