Potassium carbonate (2.58 g, 18.73 mmol) was added to a solution of 1-bromo-3-fluoro-2-nitro-benzene (2.06 g, 9.36 mmol) and benzylamine (1.13 mL, 9.364 mmol) and the resulting suspension was stirred at room temperature for 18 hours. The reaction mixture was poured onto 500 mL of ice water and extracted four times with 100 mL ethyl acetate. The combined organic fractions were dried over sodium sulfate, and concentrated in vacuo to give an oil that was purified by recrystallization from 75 mL refluxing ethanol with 3 mL water. 1.83 g of benzyl-(3-bromo-2-nitro-phenyl)-amine was collected by filtration as fine red needles. MS: 308, 309 (M+H)+.
