Procedure
4-Aminobenzoic acid (17.24 g, 0.1257 mol) was added to a stirred solution of maleic anhydride (12.33 g, 0.1257 mol) in propanone (300 ml). Stirring was continued at room temperature for 3 hours. The product, which separated as a yellow solid, was collected by suction filtration and dried on the filter: mp 217°-219° C. (Ref: K C Liu, J. Chin. Chem. Soc., 1973, 20, 163).
