実験手順

2-[2-(2-Pyridyl)-phenyl sulphinyl]-1H-benzimidazole (Example 13) (0.7 g) in dry dimethylformamide (50 ml), methyl iodide (0.34 g) and anhydrous potassium carbonate (1.1 g) were stirred at room temperature for 1.75 hours. The mixture was poured onto water, extracted into ethyl acetate, washed, dried and evaporated under reduced pressure to leave the title compound as a cream solid (0.55 g).
