To a solution of methyl 3-(acetylamino)-6-[(1E)-3-methoxy-3-oxoprop-1-en-1-yl]-2-nitrobenzoate (686 mg, 2.13 mmol) in methanol (20 mL) was added palladium-carbon powder (20 mg), and the mixture was stirred under a hydrogen atmosphere at room temperature for 5 hr. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (516 mg, yield 82%).
