Reaction Steps
7-Bromo-2-isopropylimidazo[1,2-a]pyridine-3-sulfonylchloride (500 mg, 1.481 mmol) obtained in step 1 was dissolved in acetonitrile (5.0 mL), and the solution was stirred at 50° C. for 30 minutes after adding 3,3-difluoroazetidine hydrochloride (230 mg, 1.78 mmol) and triethylamine (0.413 ml, 2.96 mmol). The reaction mixture was allowed to cool to room temperature, and a sodium hydrogen carbonate aqueous solution was added. The precipitated solid was collected by filteration to give 7-bromo-3-(3,3-difluoroazetidin-1-ylsulfonyl)-2-isopropylimidazo[1,2-a]pyridine (546 mg, yield 94%).
