실험 절차

To a stirred solution of (E)-2-bromo-4-(3-(3,5-dichloro-4-fluorophenyl)-4,4,4-trifluorobut-1-enyl)benzoic acid (300 mg, 0.638 mmol) in CH2Cl2 (5.0 mL) was added 2-amino-N-(2,2,2-trifluoroethyl)acetamide (172. mg, 0.638 mmol) followed by benzotriazol-1-yl-oxytripyrrolidinophosphonium hexafluorophosphate (PyBOP) (364.5 mg, 0.701 mmol) and DIPEA (0.32 mL, 1.914 mmol), and the resultant reaction mixture was stirred at ambient temperature for 18 h. The reaction mixture was diluted with water and extracted with CH2Cl2. The combined CH2Cl2 layer was washed with brine, dried over Na2SO4 and concentrated under reduced pressure. Purification by flash column chromatography (SiO2, 100-200 mesh; eluting with 40% ethyl acetate/petroleum ether) afforded the title compound as an off-white solid (121 mg, 31%): 1H NMR (400 MHz, CDCl3) δ 8.69 (t, J=6.0 Hz, 1H), 8.58 (t, J=6.0 Hz, 1H), 7.92 (s, 1H), 7.87 (d, J=6.4 Hz, 2H), 7.62 (d, J=8.4 Hz, 1H), 7.45 (d, J=8.4 Hz, 1H), 7.0 (m, 1H), 6.76 (d, J=15.6 Hz, 1H), 4.83 (t, J=8.0 Hz, 1H), 3.98 (m, 4H); ESIMS m/z 610.97 ([M+H]+); IR (thin film) 3303, 1658, 1166, 817 cm−1. Compounds AC76-AC80, AC96-AC102, and AC113 (Table 1) were made in accordance with the procedures disclosed in Example 15.
