実験手順

32 g of 4-(2-fluorophenyl)-1-tetralone in 75 ml of ethanol are treated with a solution of 9.26 g of hydroxylamine hydrochloride in 10 ml of water and then with 17 g of powdered sodium hydroxide. The mixture is heated to boiling under reflux for 5 minutes, again cooled and then poured into a mixture of ice and dilute hydrochloric acid. The mixture is extracted with ether and the extract obtained is washed with water. After evaporation of the solvent, there is obtained 4-(2-fluorophenyl)-1-tetralone oxime of melting point 120°.
