Reaktionsschritte

Benzimidazole (0.313 mmol) and MgO (0.376 mmol) was stirred in 1,4-dioxane (2 mL) for 10 min. at room temp. To the solution, copper iodide (0.627 mmol), palladium acetate (0.016 mmol), triphenylphosphine (0.062 mmol), and 4-bromo-N-thiazol-2-yl-benzenesulfonamide (0.313 mmol) were added. The reaction was sealed and heated to 150° C. After 7 h the reaction was cooled to 120° C. and stirred overnight. The reaction was cooled to room temperature and diluted with acetone. The solution was filtered through Celite and concentrated in vacuo. The crude was purified by reverse phase chromatography to yield 4-(1H-benzoimidazol-2-yl)-N-thiazol-2-yl-benzenesulfonamide (0.007 mmol).
