Ethanol → HCID 117899767, compound

Participants

Reaction Steps

To 60 ml of ethanol were added 4.2 g (10.3 mmol) of 5-bromopentyl-[4-chloro-2-fluoro-5-(2,2,2-trifluoroethylthio)phenyl]ether and 5.0 g (51.5 mmol) of potassium thiocyanate. The mixture was refluxed for 4 hours under heating. The mixture was allowed to cool to room temperature, and the solvent was distilled off under reduced pressure. Then extraction was conducted by adding water and ethyl acetate. The organic phase obtained was dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (developing solvent: a mixed solvent of n-hexane:ethyl acetate=10:1), to obtain 3.9 g (yield: 98%) of an intended product.
