実験手順

To a solution of 4-(methylthio)-3-(trifluoromethyl)benzyl alcohol (3.00 g, 13.5 mmol) in toluene (15 mL) was added thionyl chloride (1.18 mL, 16.2 mmol) at room temperature, and the resulting mixture was stirred for 1 hr. The reaction mixture was concentrated under reduced pressure. The residue was purified by basic silica gel column chromatography (hexane/ethyl acetate=10/1), and crystallized from hexane to give the title compound (2.54 g, yield 78%) as colorless crystals.
