Reaction Steps
Solution "A" was prepared by dissolving 42.6 grams of para-aminobenzoic acid in 300 ml acetone plus 50 ml of methyl alcohol. Solution "B" was prepared by dissolving 36.6 g of maleic anhydride in 100 ml acetone. Solution "B" was added to solution "A" in one shot at room temperature with stirring. The mixture was allowed to stir for one to two hours until a yellow precipitate was formed. The precipitate was then washed with fresh acetone and dried to yield approximately 62 grams of maleamidated benzoic acid.
