実験手順

A mixture of 1-((6-methylpyridin-2-yl)methyl)-4-nitro-3-vinyl-1H-indazole (161 mg, 0.547 mmol) and 20% palladium hydroxide on carbon (38.4 mg, 0.0547 mmol) was stirred in methanol (3 mL) under an atmosphere of hydrogen for 3 hours. The mixture was diluted with methanol and filtered through glass fiber filter paper. The filtrate was concentrated under reduced pressure to give 3-ethyl-1-((6-methylpyridin-2-yl)methyl)-1H-indazol-4-amine (142 mg).
