実験手順
2-(3-Bromo-5-(piperidin-4-ylidenemethyl)phenoxy)-5-(trifluoromethyl)pyridine (0.57 g, 1.379 mmol) and phenyl pyridazin-3-ylcarbamate (0.296 g, 1.38 mmol) were dissolved in DMSO (4 mL). Triethylamine (0.57 mL, 4.13 mmol) was added and the reaction was stirred overnight. The reaction mixture was diluted with water and extracted with ethyl acetate three times. The organic layer was washed with brine, dried over Na2SO4, and evaporated to dryness. The residue was purified by silica gel column chromatography (37% acetone in hexane) to give the title compound (0.486 g, 66%). 1H NMR (500 MHz, DMSO-d6): δ 8.78 (s, 1H), 8.45 (s, 1H), 8.27 (s, 1H), 7.93 (d, J=8.5 Hz, 1H), 7.41 (dd, J=4.75 Hz, 1H), 7.24 (s, 1H), 7.20 (s, 1H), 7.04 (d, J=9 Hz, 1H), 6.94 (s, 1H), 6.35 (s, 1H), 3.69 (m, 2H), 3.60 (m, 2H), 2.58 (m, 2H), 2.17 (m, 2H). 13C NMR (125 MHz, CDCl3): δ 165.16, 156.80, 153.50, 145.43, 140.30, 139.57, 136.97, 128.86, 128.09, 124.66, 123.35, 122.86, 122.49, 122.24, 121.98, 120.73, 111.67, 45.55, 44.52, 35.74, 29.29, 29.18; m/z (534.1, 536.1, M+ H+); HPLC: 99.0%.
