Participants

Reaction Steps

A mixture of 0.043 g (0.1 mmole) of 2-[6-(2-chloro-ethoxy)-benzoimidazol-1-yl]-4-(3-chloro-phenyl)-thiazole-5-carboxylic acid amide (I.28a), 1 mL of dimethylformamide, 0.069 g (0.5 mmole) of potassium carbonate, 0.001 g of potassium iodide and 0.033 mL (0.3 mmole) of 1-methyl-piperazine was stirred at 100 degrees for 6 hours. The mixture was cooled, the solid was removed by filtration and the filtrate purified by reverse phase silica gel chromatography, eluting with acetonitrile-water (gradient 30:70-100:0) to give 0.038 g of 4-(3-chloro-phenyl)-2-{6-[2-(4-methyl-piperazin-1-yl)-ethoxy]-benzoimidazol-1-yl}-thiazole-5-carboxylic acid amide (I.28) as a white solid.
