Procedure

A solution of NaOH (1.7 g/12 ml) was added to methyl 4-acetylbenzoate (5.04 g, 28.3 mmol) in MeOH-dioxane (2:1, 60 ml). After stirring at room temperature for 12 hr, the mixture was acidified with 5N HCl, and extracted with ethyl acetate. The organic layer was washed with brine, dried over Na2SO4. Evaporation of solvent gave 4-acetylbenzoic acid as a white solid.
