Reaction Steps

In DMSO were dissolved 2,3-dichloroquinoxaline (5.00 g, 25.1 mmol) and propane-1-sulfonamide (3.09 g, 25.1 mmol). Potassium carbonate (3.47 g, 25.1 mmol) was added and the mixture was stirred at 150° C. for 1 hour. A 1% aqueous acetic acid solution was added to the mixture and the mixture was stirred at room temperature for 3 hours. The precipitated solid was separated by filtration and the obtained solid was washed with water. The separated solid was then purified by slurrying in diisopropyl ether to give compound AA (6.01 g, 84% yield).
