Cesium carbonate → HCID 46831477, compound

Participants

Reaction Steps

To a mixture of 0.037 (0.1 mmole) of 4-(3-chloro-phenyl)-2-(6-hydroxy-benzoimidazol-1-yl)-thiazole-5-carboxylic acid amide (I.25d), 0.039 g (0.2 mmole) of 4-(2-bromo-ethyl)-morpholine and 1 mL of dimethylformamide was added 0.16 g (0.5 mmole) of cesium carbonate. The mixture was heated at 100 degrees for 3 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 0.014 g of 4-(3-chloro-phenyl)-2-[6-(2-morpholin-4-yl-ethoxy)-benzoimidazol-1-yl]-thiazole-5-carboxylic acid amide (I.26) as a white powder.
