Participants

Reaction Steps

To a solution of 4-[7-({3-chloro-4-[(3-fluorobenzyl)oxy]phenyl}amino)-2H-pyrazolo[4,3-d]pyrimidin-2-yl]benzaldehyde (80 mg) and 2-(methylsulfonyl)ethylamine hydrochloride (40 mg) in N,N-dimethylformamide (2 mL) was added acetic acid (0.02 mL), and the mixture was stirred at room temperature for 1 hr. Subsequently, sodium triacetoxyborohydride (54 mg) was added, and the mixture was stirred at the same temperature for 2 hrs. After the completion of the reaction, saturated aqueous sodium hydrogen carbonate was added, and the mixture was concentrated under reduced pressure. The residue was extracted with ethyl acetate, and the organic layer was washed with water and saturated brine and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography (ethyl acetate/methanol=5/1) to give the title compound (70 mg) as a white solid.
