Procedure

13.32 g (0.1 mol) 4-methoxybenzonitrile, 20.85 g (0.3 mol) of hydroxylamine hydrochloride and 41.40 g (0.3 mol) potassium carbonate was added to 400 mL absolute ethanol and refluxed 21 hours. The product was filtered and recrystallized from methanol to give 3.12 g (0.02 mol) of 4-methoxybenzamide oxime.
