To a solution of 3-(benzyloxy)-2-methylbenzaldehyde (200 mg) in toluene (20 mL) was added ethyl (triphenylphosphoranylidene)acetate (303 mg), and the mixture was stirred at 60° C. for 15 hr. The reaction mixture was concentrated, and diethyl ether was added. The insoluble material was filtered off, and the filtrate was concentrated. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (120 mg) as a yellow oil.
