반응 단계
2,3-Dichloroquinoxaline (26.1 g, 131.1 mmol), m-Nitrobenzene sulfonamide (26.5 g, 131.1 mmol) and potassium carbonate (18.1 g, 131.1) were dissolved in anhydrous DMSO (500 mL). The reaction was heated to 150° C. for 2 h. The reaction mixture was poured into water (400 mL), followed by addition of 2M HCl (60 mL). The product was extracted with EtOAc (3×500 mL). The organic layers were combined and washed water (2×500 mL) and brine (2×500 mL). The product was then dried with sodium sulfate to give N-(3-chloroquinoxalin-2-yl)-3-nitrobenzenesulfonamide. MS (EI) for C14H9ClN4O4S: 364.94, 366.97 (MH+)
