Procedure

Hydroxylamine hydrochloride (17.1 g, 246 mmol) and sodium acetate (20.2 g, 246 mmol) were added to 110 mL of methanol and the resulting white slurry was stirred at room temperature for 30 min. Propiophenone (30 g, 224 mmol) was added and the mixture was stirred at room temperature for 20 hours. Water (100 mL) was added and the mixture was stirred for 10 min. The product was extracted with EtOAc and the organic layer was washed with saturated NaHCO3 solution and dried over MgSO4. The solvent was evaporated in vacuo to give 32.4 g of the title compound. 1H NMR (CDCl3, 200 MHz): δ=9.21 (s, 1H), 7.60-7.72 (m, 2H), 7.38-7.50 (m, 3H), 2.91 (q, 2H, J=7.8 Hz), 1.23 (t, 3H, J=7.4 Hz).
