実験手順

To a stirred solution of (E)-(4-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-en-1-yl)naphthalen-1-yl)methanamine (0.1 g, 0.22 mmol) in CH2Cl2 (8 mL) were added 3,3,3-trifluoropropanoic acid (0.032 g, 0.24 mmol), HOBt.H2O (52 mg, 0.33 mmol), EDC.HCl (0.065 g, 0.33 mmol) and DIPEA (0.044 g, 0.45 mmol), and the resultant reaction mixture was stirred at ambient temperature for 18 h. The reaction mixture was diluted with water and extracted with EtOAc (3×30 mL). The combined EtOAc layer was washed with brine, dried over Na2SO4, and concentrated under reduced pressure. Purification by flash column chromatography (SiO2, 100-200 mesh; 15% EtOAc in n-hexane) afforded the title compound as a gummy material (60 mg, 50%): mp 151-153° C.; 1H NMR (400 MHz, CDCl3) δ 8.06 (m, 1H), 7.61 (m, 4H), 7.48 (s, 2H), 7.44 (d, J=8.0 Hz, 1H), 7.38 (m, 1H), 6.42 (m, 1H), 5.92 (br s, 1H), 4.92 (m, 2H), 4.24 (m, 1H), 3.12 (m, 2H); ESIMS m/z 554.04 ([M−H]−).
