Procedure

The compound (25) (8.5 g) and acetic acid (50 ml) were put in a reaction vessel under a nitrogen atmosphere, hydrogen peroxide (31% aqueous solution; 4.9 ml) was added dropwise thereto in the temperature range of 25° C. to 30° C., and the mixture was stirred for 2 hours at room temperature. Then, the reaction mixture was poured into a vessel containing an aqueous solution of sodium hydrogensulfite (100 ml) and ethyl acetate (200 ml), and mixed. The mixture was then allowed to stand until it had separated into organic and aqueous phases, and extraction into an organic phase was carried out. The organic phase obtained was fractionated, washed sequentially with water and brine, and then dried over anhydrous magnesium sulfate. Then, the solvent is distilled off under reduced pressure, giving 2.8 g of 4-(4-butoxycyclohexenyl)-2,3-difluorophenol (26). The yield based on the compound (25) was 49.1%.
