Reaction Steps

To a solution of 2-chloro-2',4'-difluoroacetophenone (159 g, 0.8 mol) and 2-mercaptoethanol (77.9 g, 1.0 mol) in methanol (1000 ml), potassium carbonate (138 g, 1.0 mol) was added under ice cooling, followed by stirring at room temperature for 0.5 hour. After the completion of the reaction, an insoluble matter was filtered off. The filtrate was then distilled off under reduced pressure. The residue so obtained was diluted with ethyl ether, washed with water and dried over magnesium sulfate. The solvent was distilled off under reduced pressure, whereby 2',4'-difluoro-2-(2-hydroxyethyl)thioacetophenone (190 g, yield: 98%) was obtained as a colorless oil.
