Reaction Steps

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 Et2O (5 mL) was added methylisothiocyanate (0.026 g, 0.35 mmol), and the mixture was stirred for 2 h at 25° C. The reaction mixture was concentrated under reduced pressure, and the residue was purified by flash column chromatography (SiO2, 20% EtOAc in petroleum ether). The title compound was isolated as a liquid (65 mg, 50%): 1H NMR (400 MHz, CDCl3) δ 7.39 (s, 2H), 7.25-7.18 (m, 3H), 6.58 (d, J=16.0 Hz, 1H), 6.30 (dd, J=16.0, 8.4 Hz, 1H), 5.91-5.70 (br, 2H), 4.05 (m, 1H), 3.05-2.80 (m, 6H), 2.70 (m, 1H), 1.81 (m, 1H); ESIMS m/z 492.17 ([M+H]+); IR (thin film) 3211, 1569, 1113, 806 cm−1.
