Versuchsvorschrift

To 47.5 mg of acetone oxime (0.65 mmol) in 25 ml of THF were added 73 mg (0.65 mmol) of potassium t-butoxide. The mixture was stirred at room temperature for one hour after which 210 mg of 2-di-n-propylamino-8-(2'-fluorobenzoyl)-1,2,3,4-tetrahydronaphthalene in THF were added via a syringe. The resulting mixture was refluxed for three hours after which it was cooled and poured into an aqueous solution of ammonium chloride. The mixture then was extracted with either, and the extract was dried and concentrated to obtain 343 mg of 2-di-n-propylamino-8-[2[(isopropylideneamino)oxy]benzoyl]-1,2,3,4-tetrahydronaphthalene.
