반응 단계

5-tert-Butyl-3-isobutylthiazol-2(3H)-imine (Example 16A, 1.5 g, 7.1 mmol) was dissolved in 10 mL of THF. 5-Chloro-2-fluorobenzoyl chloride (1.4 g, 7.1 mmol) was added then triethylamine (3 mL, 21.6 mmol) and the mixture stirred at room temperature for 3 hours. The reaction was diluted with EtOAc, washed with water, brine, dried over MgSO4, filtered and concentrated under reduced pressure. Purification by flash chromatography using a gradient from 0 to 40% EtOAc in hexanes afforded the title compound. 1H NMR (300 MHz, CHLOROFORM-D) δ ppm 0.98 (d, J=6.74 Hz, 6H) 1.36 (s, 9H) 2.19-2.39 (m, 1H) 4.01 (d, J=7.14 Hz, 2H) 6.63 (s, 1H) 7.05 (dd, J=10.31, 8.72 Hz, 1H) 7.35 (ddd, J=8.73, 3.97, 2.78 Hz, 1H) 8.10 (dd, J=6.74, 2.78 Hz, 1H). MS (DCI/NH3) m/z 369.2 (M+H)+.
