To a solution of 2-[3-(benzyloxy)phenyl]ethanol (700 mg) in DCM (10 mL) was added Dess-Martin periodinane (1.43 g) at 0° C. The reaction mixture was stirred for 5 hours at ambient temperature. The mixture was diluted with diethylether (25 mL), and the resulting suspension was added to saturated NaHCO3 aqueous solution (15 mL) and saturated sodium thiosulfate aqueous solution (15 mL). After the mixture was stirred for 10 minutes, the organic layer was washed with brine. The organic layer was dried over anhydrous MgSO4, filtered and evaporated in vacuo. The residue was purified by silica gel column chromatography (n-hexane:EtOAc=90:10-70:30) to give a [3-(benzyloxy)phenyl]acetaldehyde.
