Versuchsvorschrift

A solution of (4-butyl-phenyl)-[4-(2-thioxo-2,3-dihydro-benzoimidazol-1-yl)-piperidin-1-yl]-methanone (0.167 g, 0.424 mmol) in acetonitrile (5 mL) was treated with methyl iodide (0.120 g, 0.848 mmol) and potassium carbonate (0.117 g, 0.848 mmol). The reaction mixture was stirred 18 h then filtered and concentrated under reduced pressure. The crude product was purified by column chromatography on silica gel using ethyl acetate as the eluent to give (4-butyl-phenyl)-[4-(2-methylsulfanyl-benzoimidazol-1-yl)-piperidin-1-yl]-methanone (0.164 g; 95%).
