Reaction Steps

To a solution of 5-bromo-3-methyl-1H-indazole (2.0 g) in N,N-dimethylformamide (20 ml) were added (2-bromoethoxy)(tert-butyl)dimethylsilane (2.5 g) and 60% sodium hydride (682 mg) at 0° C., and the mixture was stirred at room temperature for 3 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 obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (492 mg).
