Reaction Steps
A solution of 3-hydroxy-4-methylbenzoic acid (3.0 g, 19.7 mmol) in acetic anhydride (5.6 mL) was treated with sulfuric acid (0.03 mL), heated to 70° C., cooled and diluted with water. The resulting solid was collected by filtration yielding 1.14 g (30%) of the title compound, which was used without further purification.
