반응 단계

To a suspension of 6-nitro-1-benzothiophene 1,1-dioxide (2.02 g) in ethanol (200 mL) and methanol (60 mL) was added 10% palladium carbon (50% containing water, 265 mg), and the mixture was stirred under a hydrogen atmosphere for 12 hr. The reaction mixture was filtrated, and the filtrate was concentrated under reduced pressure. The residue was recrystallized from ethyl acetate to give the title compound as a white solid (yield 1.31 g, 75%).
