Versuchsvorschrift
An aqueous solution (40 mL) of Oxone (10.4 g) is added dropwise to a stirred ice-cold solution of 4-(4-(4-fluorophenyl)-2-phenyl-1H-imidazol-5-yl)-2-(methylthio)pyrimidine, 75 (2.1 g) in methanol (40 mL). After stirring for 4 h at room temperature, the methanol is evaporated, the solution diluted with saturated aqueous sodium hydrogen carbonate and extracted with ethyl acetate. The combined organic phases are dried over sodium sulphate. Evaporation of the solvent furnishes the title compound, 76 (2.1 g).
