Toluene → HCID 117899776, compound

Participants

Reaction Steps

To 200 ml of toluene were added 20.24 g (58.5 mmol) of [2,4-dimethyl-5-(2,2,2-trifluoroethylthio)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (a compound described in PCT International Publication No. WO 2012/176856 as Compound No. 55-47) and 8.22 g (70.16 mmol) of N-methylmorpholine-N-oxide. The mixture was refluxed for 2 hours under heating. The reaction mixture was allowed to cool to room temperature, washed and dried over anhydrous magnesium sulfate. 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 10.54 g (yield: 76%) of an intended product.
