Yield:94-67-7 98%

Reaction Conditions:

with hydroxyamino hydrochloride;anhydrous sodium carbonate in ethanol;lithium hydroxide monohydrate at 20; for 2 h;

Steps:

47.1 2-hydroxybenzaldehyde oxime

At room temperature,30 mmol of 2-hydroxybenzaldehyde, 60 mmol of sodium bicarbonate,45 mmol of hydroxylamine hydrochloride were mixed in ethanol / water (50/5 mL)The reaction mixture was stirred for two hours and concentrated to remove most of the solvent.The residue was diluted with ethyl acetate and filtered directly. The filtrate was concentrated to give 3.99 g (98%) of a colorless oil.
