Reaktionsschritte

A mixture of 0.043 g (0.1 mmole) of 2-[6-(3-chloro-propoxy)-benzoimidazol-1-yl]-4-(3-chloro-phenyl)-thiazole-5-carboxylic acid amide (I.34a), 1 mL of dimethylformamide, 0.069 g (0.5 mmole) of potassium carbonate, 0.001 g of potassium iodide and 0.029 mL (0.3 mmole) of 2-(2-hydroxy-ethylamino)-ethanol was stirred at 100 degrees for 3 hours. The mixture was concentrated under reduced pressure, and diluted with 20 mL of water. The precipitate was collected by filtration and the solid triturated with diethyl ether to give 0.029 g of 2-(6-{3-[bis-(2-hydroxy-ethyl)-amino]-propoxy}-benzoimidazol-1-yl)-4-(3-chloro-phenyl)-thiazole-5-carboxylic acid amide (I.35) as a white powder. MH+/Z=516
