1-(3-Chlorophenyl)ethanamine (553 mg, 3.55 mmol), 2,4-difluoronitrobenzene (565 mg, 3.55 mmol) and N,N-diisopropylethylamine (918 mg, 7.10 mmol) were stirred at room temperature in dry acetonitrile (20 mL) for 6 h. The solvent was evaporated and the residue was dissolved in dichloromethane and washed with water. The dichloromethane was evaporated to collect the title compound (600 mg, 57% yield). 1H NMR (400 MHz, CDCl3): δ 8.49 (s, 1H), 8.23 (m, 1H), 7.04 (m, 4H), 6.36 (t, 1H), 6.22 (d, 1H), 4.56 (m, 1H), 1.64 (d, 3H); MS (ESI) m/z: Calculated for C14H13ClFN2O2: 295.06; Observed: 295.0 (M++1).
