Water → (E)-3,3,3-Trifluoro-N-(5-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-enyl)-2,3-dihydro-1H-inden-1-yl)propanamide

To a stirred solution of (E)-5-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-enyl)-2,3-dihydro-1H-inden-1-amine (0.1 g, 0.23 mmol) in CH2Cl2 (10 mL) were added trifluoropropionic acid (0.044 g, 0.34 mmol), EDC.HCl (0.038 g, 0.35 mmol), HOBt.H2O (0.07 g, 0.46 mmol) and DIPEA (0.074 g, 0.57 mmol), and the reaction mixture was stirred for 16 h at 25° C. The reaction mixture was diluted with CH2Cl2 and washed with H2O. The combined organic layer was washed with brine, dried over anhydrous Na2SO4, and concentrated under reduced pressure. The crude material was purified by flash column chromatography (SiO2, 15% EtOAc in petroleum ether) to afford the title compound as a liquid (65 mg, 65%): 1H NMR (400 MHz, CDCl3) δ 7.39 (s, 2H), 7.25-7.20 (m, 3H), 6.34 (d, J=16.0 Hz, 1H), 6.30 (dd, J=16.0, 8.0 Hz, 1H), 5.81 (br, 1H), 5.48 (m, 1H), 4.10 (m, 1H), 3.10 (m, 2H), 2.86-3.07 (m, 2H), 2.86 (m, 1H), 1.81 (m, 1H); ESIMS m/z 529.02 ([M+H]+); IR (thin film) 3283, 1652, 1241, 811 cm−1.
