Procedure

A solution of 3-[2-(4-hydroxyphenyl)ethyl]glutaric acid (600 mg) in acetic anhydride (15 ml) is heated in a bath at 120° C. for 2.0 hours. It is evaporated in vacuo and the residue is crystallized from dichloromethane-hexane to afford 495 mg of 3-[2-[4-(acetyloxy)phenyl]ethyl]glutaric anhydride, melting point 97°-99° C.
