To a mixture of 0.022 g (0.05 mmole) of 2-[6-(4-methyl-piperazin-1-ylmethyl)-benzoimidazol-1-yl]-4-phenyl-thiazole-5-carboxylic acid (I.1b), 0.023 g (0.06 mmole) of 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium, 3-oxide, hexafluorophosphate(1-) (1:1), 0.004 g of ammonium chloride and 1 mL of dimethylformamide was added 0.026 mL (0.15 mmole) of ethyldiisopropylamine. The mixture was stirred at ambient temperature for 1 hour. Solids were removed by filtration and the filtrate purified by reverse phase silica gel chromatography, eluting with acetonitrile-water (gradient 10:90-90:10) to give 0.014 g of 2-[6-(4-methyl-piperazin-1-ylmethyl)-benzoimidazol-1-yl]-4-phenyl-thiazole-5-carboxylic acid amide (I.1) as a white powder. MH+/Z=433.
