Tetrahydrofuran → HCID 117899660, compound

Participants

Reaction Steps

To 60 ml of tetrahydrofuran were added 3.9 g (10.1 mmol) of 5-thiocyanatopentyl-[4-chloro-2-fluoro-5-(2,2,2-trifluoroethylthio)phenyl]ether and 4.5 g (31.6 mmol) of trifluoromethyltrimethylsilane. Thereto was added 1.0 ml (1.04 mmol) of tetrahydrofuran solution (1 mol/liter) of tetra-n-butylammonium fluoride at 0° C., and reaction was carried out. The mixture was stirred overnight at room temperature. Then, the solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography (developing solvent: a mixed solvent of n-hexane:ethyl acetate=20:1), to obtain 2.60 g (yield: 60%) of an intended product.
