A mixture of 3-(benzyloxy)-5-methylbenzaldehyde (948 mg), hydroxyl ammonium chloride (320 mg), sodium bicarbonate (837 mg), and ethanol (10 mL) was stirred overnight at room temperature. To the reaction mixture, water and brine were added, followed by extraction with ethyl acetate. The extract was washed with brine and dried over anhydrous magnesium sulfate, and then, the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to obtain the title compound (804 mg).
