Methyl 4-(methylamino)-3-nitrobenzoate → Methyl 3-amino-4-(methylamino)benzoate

Participants

Reaction Steps

After dissolving 4-methylamino-3-nitrobenzoic acid methyl ester (540 mg, 2.5 mmol) in ethyl acetate-methanol (2:1) (20 ml), 10% palladium-carbon powder (5 mol %) was added thereto under a nitrogen atmosphere. The mixture was stirred for 4 hours under a hydrogen atmosphere, and then the reaction mixture was filtered through celite. The filtrate was concentrated under reduced pressure to obtain 3-amino-4-methylaminobenzoic acid methyl ester. The compound was identified by LC-MS.
