Procedure: A solution of methyl 2-(4-hydroxyphenyl)cyclopropanecarboxylate (0.158 g, 0.822 mmol), (3-phenoxyphenyl)methanol (0.150 g, 0.747 mmol) and tributylphosphine (0.301 g, 1.49 mmol) in toluene (15 mL) was stirred, 1,1′-(azodicarbonyl)dipiperidine (0.375 g, 1.49 mmol) was added, and the mixture was stirred at room temperature for 60 hr. Hexane (15 mL) was added to the reaction mixture, and the precipitated insoluble material was filtrated. The filtrate was concentrated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate:hexane=0:100-30:70) to give the title compound (0.221 g, yield 72%) as colorless crystals. the precipitated insoluble material was filtrated The filtrate was concentrated under reduced pressure the residue was purified by silica gel column chromatography (ethyl acetate:hexane=0:100-30:70)

Procedure: Methyl 2-[4-(acetyloxy)phenyl]cyclopropanecarboxylate (2.26 g, 9.65 mmol) was dissolved in a mixed solvent of methanol (80 mL) and water (20 mL), and ammonium acetate (5.95 g, 77.2 mmol) was added. The mixture was stirred at room temperature for 10 hr and further stirred at 60° C. for 8 hr. The reaction mixture was concentrated under reduced pressure, and the residue was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=5:95-40:60) to give the title compound (1.78 g, yield 96%) as colorless crystals. was added further stirred at 60° C. for 8 hr The reaction mixture was concentrated under reduced pressure the residue was extracted with ethyl acetate The extract was washed with saturated brine dried over anhydrous magnesium sulfate concentrated under reduced pressure The residue was purified by silica gel column chromatography (ethyl acetate:hexane=5:95-40:60)
