Reaction Steps

A solution of 3-(7-chloro-1-(2,6-difluorophenyl)-4-methoxy-1H-pyrazolo[4,3-c]pyridin-3-yl)phenol (30 mg), potassium carbonate (7 mg) and 2-bromoethanol (21 μL) in DMF (3 mL) was stirred at 70° C. for 5 hr. The mixture was allowed to be cooled to room temperature, potassium carbonate (107 mg) and 2-bromoethanol (55 μL) were added thereto, and the mixture was stirred overnight at 7° C. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (15 mg).
