실험 절차

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-one (1 g, 2.39 mmol) in MeOH (10 mL) were added ammonium acetate (NH4OAc, 1.84 g, 23.9 mmol) and NaBH3CN (0.44 g, 7.17 mmol,) and the reaction mixture was heated at reflux for 16 h. The reaction mixture was concentrated under reduced pressure, and the residue was diluted with water and extracted with EtOAc. The combined organic extracts were washed with water and saturated aqueous NaHCO3 solution, dried over anhydrous Na2SO4, and concentrated under reduced pressure to afford the title compound as a liquid (500 mg, crude): 1H NMR (400 MHz, DMSO-d6) δ 7.85 (s, 2H), 7.40 (s, 1H), 7.30 (s, 2H), 6.71 (s, 2H), 4.78 (m, 1H), 4.2 (m, 1H), 2.80 (m, 1H), 2.73 (m, 1H), 1.60 (m, 2H); ESIMS m/z 419.02 ([M+H]+); IR (thin film) 2924, 1552, 1112, 807 cm−1.
