Reaction Steps

1,4-Pentadien-3-ol (200 mg, 2.38 mmol) and IBX (999 mg, 3.57 mmol) were dissolved in DCE (15 mL) and heated at 70° C. for 3 h. The reaction mixture was filtered, diluted with MeOH (10 mL) and 2-fluoro-1-fluoromethyl-ethylamine (226 mg, 2.38 mmol) was added. The reaction mixture was stirred at 70° C. for 3 h. Isocyanate resin was added and the reaction mixture stirred at room temperature for 6 h, filtered and concentrated in vacuo to give the crude title compound (160 mg, 38%) as an orange gum. LCMS (ES+): 178.1 [MH]+.
