To a mixture of 0.048 g (0.1 mmole) of 4-(3-chloro-phenyl)-2-[6-(4-methyl-piperazin-1-ylmethyl)-benzoimidazol-1-yl]-thiazole-5-carboxylic acid, 0.046 g (0.12 mmole) of 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium, 3-oxide, hexafluorophosphate(1-) (1:1), 0.008 g (0.15 mmole) of ammonium chloride and 1 mL of dimethylformamide was added 0.052 mL of diisopropylethylamine. The mixture was stirred at ambient temperature for 1 hour, filtered and then purified by reverse phase silica gel chromatography, eluting with acetonitrile-water (gradient 10:90-90:10) to give 0.027 g of 4-(3-chloro-phenyl)-2-[6-(4-methyl-piperazin-1-ylmethyl)-benzoimidazol-1-yl]-thiazole-5-carboxylic acid amide (I.2) as a white solid.
