実験手順

Potassium carbonate (1.5 mmol) was added to a solution of 6-hydroxy-N,2-dimethylbenzofuran-3-carboxamide (1 mmol) in 5 ml DMF. After 30 mins, 2,4-dichloropyrimidine (1 mmol) was added and the reaction mixture was stirred overnight at 60° C. Water was added. The resultant solid was filtered, washed with water, and dried to give 6-(2-chloropyrimidin-4-yloxy)-N,2-dimethylbenzofuran-3-carboxamide in a yield of 82%, as a solid, which was used in the next step without further purification.
