Benzoic acid, 2-(methylamino)-3-nitro-, methyl ester → Benzoic acid, 3-amino-2-(methylamino)-, methyl ester

Participants

Reaction Steps

To a suspension of methyl 2-(methylamino)-3-nitrobenzoate (2.10 g, 10.0 mmol) in tetrahydrofuran (40 mL) was added palladium on carbon (210 mg), and the mixture was purged with hydrogen and stirred under balloon pressure hydrogen for 2 hr at room temperature. The catalyst was removed by filtration, and the filtrate was concentrated in vacuo to give the title compound (1.80 g, 10.0 mmol, 100%) as a pale yellow oil.
