実験手順

To a solution of 4-chloro-3-iodo-1-trityl-1H-pyrazolo[4,3-c]pyridine (1.7 g) in THF (20 mL) was added sodium methoxide methanol solution (1.5 M, 2.7 mL) at room temperature, and the mixture was stirred at 50° C. for 2 hr. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to give the title compound (1.6 g).
