Versuchsvorschrift

To a solution of N-methyl-N-(2-nitrophenyl)methanesulfonamide (900 mg, 3.91 mmol) in methanol (5 mL) was added palladium on carbon (10% by weight, 416 mg, 0.39 mmol). The solution was purged with hydrogen and then stirred for 4 hours under 1 atm of hydrogen. The crude reaction was filtered, concentrated and purified by chromatography to provide N-(2-aminophenyl)-N-methylmethanesulfonamide (540 mg, 60% yield). Product not characterized.
