Procedure
Acetophenone (5.0 mL, 43 mmol) was dissolved in methanol (50 mL). Hydroxylamine hydrochloride (6.1 g, 88 mmol) was added to the mixture followed by 10N sodium hydroxide (10 mL, 100 mmol). Reaction was stirred at room temperature for 20 minutes. 10N Sodium hydroxide (5 mL, 50 mmol) was added to the mixture. Reaction was heated at reflux for 1 hour. Mixture was cooled to room temperature and stirred for 4 hours. Reaction mixture was concentrated in vacuo. Residue was treated with water. Mixture was extracted 2× diethyl ether. Combined extracts were washed 1× water, 1× brine. Organic layer was dried (magnesium sulfate), filtered and concentrated. Title compound was obtained as white solid in 76% yield. MS m/e (M+H)+=136.0.
