Under an argon atmosphere, to a solution of 2-[3-(benzyloxy)propyl]-3H-imidazo[4,5-b]pyridine (2 g) in DMF (40 mL) was added 60% sodium hydride (0.299 g), and the mixture was stirred under ice-cooling for 30 min. Then, dimethylsulfuric acid (0.75 mL) was added, and the mixture was stirred at room temperature for 17 hr. To the reaction mixture was added methanol (5 mL), and the mixture was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/methanol) to give the title compound (1.2 g).
