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 0.025 mL (0.3 mmole) of pyrrolidine was stirred at 100 degrees for 6 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 0.036 g of 4-(3-chloro-phenyl)-2-[6-(3-pyrrolidin-1-yl-propoxy)-benzoimidazol-1-yl]-thiazole-5-carboxylic acid amide (I.34) as a white solid. MH+/Z=482
