실험 절차
In the same apparatus as in Example 1 5-methyl-α-n-pentyl-furfuryl alcohol (40 parts), ethylene glycol (20 parts) and a buffer solution prepared from water (1200 parts) and sodium acetate (0.5 part) and adjusted to pH 5.2 with acetic acid were charged, and the resultant mixture was stirred at 100° C. in a nitrogen stream for 20 hours. The reaction mixture was cooled and extracted with toluene. The extract was concentrated to give 2-n-pentyl-3-hydroxy-3-methyl-4-cyclopentenone in a yield of 84 %.
