Procedure
A solution of 3-(4-hydroxyphenyl)glutaric acid (800 mg) in acetic anhydride (15 ml) is heated at 100° C. for 2.5 hours and evaporated to dryness in vacuo. The residual solid is crystallized from chloroform-hexane to afford 600 mg of 3-(4-acetyloxyphenyl)glutaric anhydride, melting point 140°-143° C.
