2,4-Difluoronitrobenzene (2.9 g, 18.1 mmol), 3-Bromobenzylamine (2.6 g, 18.1 mmol) and N,N-diisopropylethylamine (2.4 g, 18.1 mmol) were stirred in acetonitrile (25 mL) at room temperature for 2 hours. The solvent was evaporated and the crude mixture was dissolved in dichloromethane and washed with water. The dichloromethane was evaporated in vacuo to collect the title compound (4.8 g, 95% yield). 1H NMR (400 MHz, CDCl3): δ 8.55 (s, 1H), 8.25 (dd, 1H), 7.32-7.21 (m, 4H), 6.41 (m, 2H), 4.50 (d, 2H).
