Versuchsvorschrift
Into the same flask as used in Example 1, 2-n-pentyl-3-hydroxy-3-methyl-4-cyclopentenone (0.1 mol; 1 part), n-propanol (5 parts) and p-toluenesulfonic acid (1/20 part) were charged, and the mixture was stirred at a temperature of 40° to 70° C. for 5 hours. After completion of the reaction, the mixture was treated in the same manner as in Example 25 to obtain 2-n-pentyl-3-methyl-4-n-propoxy-2-cyclopentenone. Yield, 96%. nD19 1.4792.
