YieldReaction ConditionsOperation in experiment
75% With palladium 10% on activated carbon; hydrogen; In methanol; ethanol; for 12.0h; Reference Example 119 2,3-Dihydro-1-benzothiophene-6-amine 1,1-dioxide To a suspension of <strong>[19983-44-9]6-nitro-1-benzothiophene 1,1-dioxide</strong> (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%). 1H-NMR (CDCl3)delta: 3.25 (2H, t, J=6.9 Hz), 3.44-3.49 (2H, m), 3.93 (2H, brs), 6.84-6.87 (1H, m), 6.94-6.95 (1H, m), 7.12 (1H, d, J=8.1 Hz).

With hydrogen; acetic acid;palladium 10% on activated carbon; In ethyl acetate; A solution of <strong>[19983-44-9]6-nitro-1-benzothiophene 1,1-dioxide</strong> (1.04 g) in acetic acid (50 ml) and ethyl acetate (50 ml) was hydrogenated(10% palladium on carbon (130 mg, 50% wet). The catalyst was removed by filtration and washed with ethyl acetate. The filtrate and washings were evaporated under reduced pressure to give the title compound (1.1g). LCMS RT=1. 50 min
