Versuchsvorschrift

To a mixture of 2-(2-ethylsulfanyl-phenyl)-5-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-1H-benzimidazole (97 mg) and DMF (10 mL), sodium hydride (11 mg) and iodomethane (16 μL) were added under ice-cooling. The mixture was heated to room temperature, and stirred for 5 hours. The reaction mixture was diluted with water, and extracted with ethyl acetate. The combined organic layer was dried over sodium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 35 mg of 2-(2-ethylsulfanyl-phenyl)-1-methyl-6-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-1H-benzimidazole (hereinafter, Present Compound 304) and 80 mg of 2-(2-ethylsulfanyl-phenyl)-1-methyl-5-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-1H-benzimidazole (hereinafter, Present Compound 305).
