실험 절차

To a stirred solution of (E)-(4-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-en-1-yl)phenyl)hydrazine (0.1 g, 0.3 mmol) in CH2Cl2 (10 mL) was added DIPEA (65 mg, 0.51 mmol), HOBt.H2O (59 mg, 0.38 mmol), EDC.HCl (73 mg, 0.38 mmol) and cyclopropanecarbonyl chloride (0.024 g, 0.28 mmol), and the reaction mixture was stirred at ambient temperature for 1 h. The reaction mixture was diluted with satd aq NaHCO3 solution and extracted with CH2Cl2. The combined CH2Cl2 layer was washed with brine, dried over anhydrous Na2SO4, and concentrated under reduced pressure. Purification by flash column chromatography (SiO2; 5-25% EtOAc in petroleum ether) afforded the title compound as a solid (65 mg, 55%): mp 138-140° C.; 1H NMR (400 MHz, CDCl3) δ 9.81 (s, 1H), 7.90 (s, 1H), 7.84 (s, 2H), 7.34 (d, J=8.4 Hz, 2H), 6.65 (d, J=15.6 Hz, 1H), 6.61 (m, 1H), 6.57 (s, 1H), 6.48 (dd, J=15.6, 8.8 Hz, 1H), 4.74 (m, 1H), 1.64 (m, 1H), 0.75 (m, 4H); ESIMS m/z 461.32 ([M−H]−).
