実験手順

To a stirred solution of 4-chloro-3-nitrocinnamide (275 mg, 0.814 mmol) from Example 32A in 1.0 mL of DMF was added potassium carbonate (169 mg, 1.22 mmol), followed by the dropwise addition of 2,4-dichlorothiophenol (146 mg, 0.815 mmol). The mixture was then stirred at room temperature for 60 minutes. Completion of the reaction was indicated by the TLC. Water was then added to precipitate the product. Filtration, washing with cold water, and drying in a vacuum oven afforded 350 mg (0.728 mmol, 89%) of the title compound as a light yellow solid. 1H NMR (d6-DMSO, 300 MHz) δ 2.05 (s, 3H), 3.42-3.50 (br m, 4H), 3.50-3.64 (br m, 2H), 3.64-3.79 (br m, 2H), 6.83 (d, J=8.7 Hz, 1H), 7.44 (d, J=15.3 Hz, 1H), 7.55 (d, J=15.3 Hz, 1H), 7.63 (dd, J=2.7, 8.7 Hz, 1H), 7.83 (d, J=8.7 Hz, 1H), 7.93 (d, J=8.7 Hz, 1H), 7.96 (d, J=2.7 Hz, 1H), 8.69 (d, J=1.8 Hz, 1H). MS (DCI/NH3) (M+H)+ at m/z 497, 499, 501. Analysis calculated for C21H19N3O4Cl2S1 0.82H2O: C, 50.94; H, 4.20; N, 8.49. Found: C, 50.91; H, 4.21; N, 8.69.
