Procedure

To 400 ml of ethanol and 180 ml of water were added 80 g (0.43 mole) of 2-methoxy-1-naphthaldehyde, 66 g (0.81 mole) of sodium acetate and 35.5 g (0.51 mole) of hydroxylamine hydrochloride, and the mixture was refluxed by heating for 2 hours. After the reaction, the reaction mixture was added to 1 liter of water. The precipitated crystals were collected by filtration to obtain 85 g (0.42 mole) of 2-methoxy-1-naphthaldoxime.
