Reaction Conditions

Reaction Steps

3-Iodo-7-nitro-1H-indazole (2.50 g, 8.65 mmol) prepared in Step A was dissolved in acetone (50 mL). Potassium hydroxide (0.73 g, 12.97 mmol) and 4-methoxybenzylchloride (1.63 g, 10.38 mmol) were added in drops thereto at 0° C., and the mixture was stirred for 2 h. After completion of the reaction, the reaction mixture was diluted with water, extracted with ethyl acetate, washed with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and filtered. The solvent was removed under reduced pressure, and the residue was purified by column chromatography to give the title compound (3.2 g, Yield 91%).
