Reaction Steps

In a 50 ml three-neck flask fitted with a thermometer, a condenser and a stirrer were placed 2-hexylidenecyclopentanone (15 g) synthesized in Reference Example 5 and bromine (0.03 g), followed by 6 hours of the reaction at 100-120° C. The crude product was purified by column chromatography (hexane/ethyl acetate: 95/5) to obtain 12.5 g of 2-hexyl-2-cyclopentenone (GC purity: 98.5%).
