Benzoic acid, 2-(acetylamino)-4-nitro- → 4-Amino-2-acetamidobenzoic acid

Participants

Reaction Steps

A reaction mixture prepared by dissolving 575 mg of 4-nitro-N-acetyl-anthranilic acid in 200 ml of ethyl acetate and by mixing the resultant solution with 100 mg of a 10% Pd-C catalyst was stirred at room temperature in a hydrogen gas atmosphere for 4 hours. Then, the reaction mixture was filtered through a Celite filter to remove the catalyst, and the catalyst was washed with ethyl acetate. The total amount of the filtrate was collected and concentrated under a reduced a silica gel column chromatography. A final product consisting of 4-amino-N-acetyl-anthranilic acid was obtained in an amount of 450 mg.
