Procedure

3-[2,4-Bis(methoxymethoxy)phenyl]-2-cyclohexen-1-one (200 mg), hydroxylamine hydrochloride (72 mg) and triethylamine (0.14 ml) were heated under reflux in ethanol (10 ml). After 3 hr, the cooled reaction mixture was partitioned between water and ethyl acetate. The organic layer was dried over magnesium sulfate and evaporated in vacuo to furnish the title compound as an oil (206 mg, 99%). m/z (ES+) 308 (M+H)+.
