ChEBI: A amidobenzoic acid that consists of benzoic acid bearing an acetamido substituent at position 4.

Into a 2 L, 3-necked flask set in a tub and equipped with a stirrer, an air condenser (drying tube), thermometer, was placed 860 ml of water, 43.0 g of MgSO4 and 43.0 g of sodium acetate and heated on water bath. Into heated solution to 70°C stirring 43.0 g of N-p-tolylacetamide were added. Then 136.0 g of KMnO4 by small portions were added at 75°-80°C. The reaction mixture allow to stand for 6 h and stirring was continue till the solution became colorless. Hot solution was filtered and filtrate treated hydrochloric acid to slightly acidic pH. After that 44.0 g (85%) of p-acetoaminobenzoic acid was obtained as white precipitate, melting point 250°C.
