Reaction Steps

6-Bromo-3H-imidazo[4,5-b]pyridine 4-oxide (1.88 g, 8.82 mmol) in N,N-dimethylformamide (12 mL) was heated to 50° C., mixed with methansulfonyl chloride (8.00 mL, 103 mmol) and stirred at 73° C. for 3 hours. The reaction mixture was cooled with ice and gradually poured into saturated aqueous sodium hydrogen carbonate (75 mL), and the precipitated solid was collected by filtration, washed with water and chloroform and dried under reduced pressure to give the title compound as a dark brown solid (1.07 g, yield 52%).
