実験手順: To a solution of 1-phenyl-2-(phenylthio)ethanone (2.1 g) in acetic acid (20 mL) was added bromine (0.5 mL), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was concentrated under reduced pressure, water was added to the residue, and the mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give the title compound as a yellow oil (yield 2.9 g, about 100%). The reaction mixture was concentrated under reduced pressure, water was added to the residue the mixture was extracted with ethyl acetate The extract was washed with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine dried over anhydrous magnesium sulfate concentrated under reduced pressure

実験手順: To a suspension of 2-bromoacetophenone (10 g) and potassium carbonate (7.1 g) in ethanol (150 mL) was added thiophenol (5.2 mL) under ice-cooling, and the mixture was stirred at room temperature for 12 hr. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. Water was added to the residue, and the mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine in this order, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent:hexane-ethyl acetate=15:1) to give the title compound as yellow crystals (yield 11 g, 98%). cooling The insoluble material was filtered off the filtrate was concentrated under reduced pressure Water was added to the residue the mixture was extracted with ethyl acetate The extract was washed with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine in this order dried over anhydrous magnesium sulfate concentrated under reduced pressure The residue was purified by silica gel column chromatography (eluent:hexane-ethyl acetate=15:1)

実験手順: To 300 mL of pyridine was added a-bromoacetophenone (150 g, 750 mmol) and thiophenol (83 g, 750 mmol). The mixture was heated at reflux for six hours. The pyridine was evaporated and the residue dissolved in ethyl acetate. The ethyl acetate solution was washed exhaustively with 1 N sodium hydroxide, then with 1 N hydrochloric acid, dried over magnesium sulfate, filtered, and evaporated to yield a brown oil. The product was crystallized from ethanol at 0° C. to yield 116 g of the title compound.
