Reaction Conditions

Reaction Steps

Methyl iodide (41 μl) and potassium carbonate (114 mg) were added to a 1,4-dioxane (2.5 ml) solution containing 3-fluoro-5-nitro-1H-indazole (100 mg), followed by stirring at 100° C. for 2 hours. Ethyl acetate was added to the reaction solution. An insoluble precipitate was removed by filtration, the solvent was distilled away under reduced pressure, and the obtained residue was purified by silica gel chromatography (n-hexane:ethyl acetate=1:0 to 1:1). 3-Fluoro-1-methyl-5-nitro-1H-indazole was thus obtained.
