In the same apparatus as in Example 1, 5-methyl-allyl-furfuryl alcohol (50 parts) and a buffer solution prepared from water (1500 parts) and dipotassium monohydrogen phosphate (1.7 parts) and adjusted to pH 5.1 with phosphoric acid were charged, and the resultant mixture was stirred at 100° C. in a nitrogen stream until the starting compound was consumed. The reaction mixture was treated as in Example 1 to give 2-allyl-3-hydroxy-3-methyl-4-cyclopentenone in a yield of 80 %.
