Dissolve 100 g (0.57 mol) of 6-methoxy-1-tetralone in 2.5 litres of a mixture of ethanol/water: 80/20. There are then added, at ambient temperature, 85 g (1.04 mol) of sodium acetate and 43 g (0.62 mol) of hydroxylamine hydrochloride. Heat the suspension at reflux for 4 hours. Dilute the mixture with 5 litres of water and extract with ethyl ether, wash with water, dry over magnesium sulphate and filter. After evaporating off the solvent, 99 g of a beige solid are obtained.
