Reaction Steps

To a solution of 4-[(4-chlorobenzyl)oxy]-1-[2-(2-hydroxyethyl)-3-methyl-2H-indazol-5-yl]pyridin-2(1H)-one (30 mg) in N,N-dimethylformamide (2 ml) was added 60% sodium hydride (3.51 mg) at 0° C., and the mixture was stirred at room temperature for 30 min. To the obtained reaction mixture was added (2-bromoethyl)methyl ether (15.3 mg), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was added to 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 (NH, hexane/ethyl acetate) to give the title compound (28.1 mg).
