Reaction Steps

1-(5-Bromo-pyridin-2-yl)-4,4,5,5,5-pentafluoro-pent-1-en-3-one (936.0 mg, 2.8 mmol) prepared in Step 3, 2-chlorophenylhydrazine hydrochloride (508.0 mg, 2.8 mmol), and piperidine (560.0 uL, 5.7 mmol) were added to ethanol (28.4 mL). The reaction mixture was stirred at 60° C. for 2 hours, concentrated under reduced pressure, and then ethyl acetate was added thereto. The mixture was washed with distilled water, dried on anhydrous magnesium sulfate, and then concentrated under reduced pressure to give a yellow liquid residue. The resulting residue was purified by silica gel column chromatography (eluent: ethyl acetate/n-hexane=1/10) to give 450.0 mg of the titled compound as a yellow liquid.
