Versuchsvorschrift

150 ml of a saturated solution of hydrogen chloride in ether are added to a solution of 149 g of 4-(tetrahydropyran-2-yloxy)-2-(3,4-dichlorophenyl)-1-aminobutane in 700 ml of methanol. The mixture is stirred for 1/2 hour at room temperature and concentrated under vacuum and the residue is taken up in 500 ml of water and washed with ether. The aqueous phase is rendered alkaline with a solution of sodium hydroxide and extracted twice with methylene chloride. The organic phases are dried over MgSO4, filtered and concentrated under vacuum. The residue is taken up in 400 ml of isopropyl ether and the mixture is stirred for one hour at room temperature. The precipitate is filtered off and washed with ether.
