実験手順

To a stirred solution of (E)-2-amino-1-(5-(3-(3,5-dichloro-4-fluorophenyl)-4,4,4-trifluorobut-1-enyl)-1H-indol-1-yl) ethanone (0.04 g, 0.09 mmol) in DCM (5.0 ml) was added 3,3,3-trifluoropropanoic acid (17.5 mg, 0.136 mmol), PyBOP (70 mg, 0.135 mmol) and DIEA (29 mg, 0.225 mmol) and the reaction was stirred at RT for 16 h. The reaction mixture was diluted with DCM, and the DCM layer was washed with water and saturated brine solution. The separated DCM layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford the crude compound, which was purified by column chromatography (SiO2, 100-200 mesh; 10% ethyl acetate/petroleum ether) to afford the title compound as an off-white solid (30 mg, 60%): mp 121-126° C.; 1H NMR (400 MHz, CDCl3) δ 8.33 (br, 1H), 7.59 (s, 1H), 7.45 (m, 4H), 6.72 (d, J=3.6 Hz, 3H), 6.39 (m, 1H), 4.71 (t, J=7.2 Hz, 2H), 4.15 (m, 1H), 3.51 (m, 1H), 3.28 (m, 1H); ESIMS m/z 553.06 ([M−H]−).
