Procedure

Into the same flask as used in Example 1, dl-3-hydroxy-2,3-dimethyl-4-cyclopentenone (12.6 g) and acetic anhydride (30 g) were charged, and the resultant mixture was stirred at 80°-100° C. for 3 hours. After completion of the reaction, the reaction mixture was subjected to the same work-up as in Example 11, followed by purification to give 16.2 g of dl-3-acetoxy-2,3-dimethyl-cyclopentenone. Yield, 96.5%. B.P., 52°-55° C./0.4-0.5 mmHg.
