Reaction Steps

To a solution of methyl 6-fluoro-5-[(1E)-3-methoxy-3-oxoprop-1-en-1-yl]-2-methyl-2H-indazole-4-carboxylate (430 mg, 21.47 mmol) in THF/methanol (5 mL/5 mL) was added palladium-carbon powder (86 mg), and the mixture was stirred under a hydrogen atmosphere at room temperature for 18 hr. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (407 mg, yield 94%).
