Procedure

To a solution of 100 mg of 3-hydroxy-3-methyl-7-(p-hydroxy-m-methoxyphenyl)-5-heptanolide in 1 ml of pyridine was added 1 ml of acetic anhydride and the mixture was stirred overnight at room temperature. After completion of the reaction, water was added to the reaction mixture and the mixture was extracted with ethyl acetate. Evaporation of the solvent from the extract yielded the desired compound as a colorless oily substance.
