Versuchsvorschrift

1,2,3,4-Tetrahydro-6-acetoxy-2-[(4-phenyl-1-piperazinyl)methyl]-1-naphthalenol (3.96 g) in 32 ml of 8% methanolic potassium hydroxide is refluxed for 3 minutes under argon, cooled to room temperature and diluted with sufficient water to effect solution. Excess aqueous ammonium chloride solution is added dropwise, with stirring, and the reaction mixture is extracted several times with methylene chloride. The organic extracts are dried, filtered and evaporated to give the title compound.
