To a mixture of 4-methyl-3-nitrobenzaldehyde (3.00 g), hydroxylamine hydrochloride (1.64 g), ethanol (30 mL) and water (15 ml) was added sodium acetate (2.24 g) at room temperature, and then the mixture was stirred at room temperature for 1 hour. The reaction mixture was extracted with water and ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and concentrated under reduced pressure to obtain 5-hydroxyiminomethyl-2-methylnitrobenzene (2.77 g).
