Tetrahydrofuran → 6-Trifluoromethylthiohexyl-[2,4-dichloro-5-(2,2,2-trifluoroethylthio)phenyl]ether

Participants

Reaction Steps

To 30 ml of tetrahydrofuran were added 1.04 g (2.49 mmol) of 6-thiocyanatohexyl-[2,4-dichloro-5-(2,2,2-trifluoroethylthio)phenyl]ether and 1.06 g (7.45 mmol) of trifluoromethyltrimethylsilane. Thereto was added 0.25 ml (concentration: 1 mol/liter, 0.25 mmol) of tetrahydrofuran solution of tetra-n-butylammonium fluoride at 0° C., and reaction mixture was stirred for 2 hours 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 0.73 g (yield: 64%) of an intended product.
