実験手順

Analogously to the production of 5-chloro-1H-indazol-4-ylamine, the regioisomeric mixture of the previous reaction (1.0 g, 5.64 mmol)) is reacted with 100 mg of palladium on carbon in methanol under hydrogen atmosphere for 16 hours at room temperature. After purification on silica gel with hexane/ethyl acetate (33% hexane, then 100% ethyl acetate), 53 mg (6% of theory) of 5-methyl-1H-indazol-4-ylamine is obtained.
