4-Methylcyclohexanone (2.0 g, 17.8 mmol) was mixed with hydroxylamine hydrochloride (1.86 g, 26.8 mmol) and sodium acetate (2.63 g, 32.0 mmol) in a mixture of EtOH (20 mL) and water (12 mL). The mixture was refluxed for 5 h. All solvent was removed under reduced pressure and the residue was partitioned between ethyl acetate and water. After separation, the organic layer was washed with brine, dried over anhydrous sodium sulfate. After filtration and concentration, the crude product was used for the next step without further purification.
