2,2,2-Trifluoro-1-(2,4-difluorophenyl)ethanone (1.59 g, 7.57 mmol), 1-phenylethanamine (0.92 g, 7.57 mmol) and N,N-diisopropylethylamine (1.95 g, 15.1 mmol) were stirred at room temperature in dry acetonitrile (50 mL) for 20 h. The solvent was evaporated and the residue was dissolved in dichloromethane and washed with water. The dichloromethane was evaporated and purified by silica chromatography in 20% ethyl acetate in hexanes to collect the title compound (0.28 mg, 12% yield). 1H NMR (400 MHz, CDCl3): δ 9.32 (s, 1H), 7.80 (t, 1H), 7.31 (m, 5H), 6.33 (t, 1H), 6.22 (d, 1H), 4.58 (m, 1H), 1.62 (d, 3H).
