Versuchsvorschrift

A solution of the oxime prepared above (4.0 g) in ether (50 ml) was added slowly to a stirred suspension of lithium aluminium hydride (0.9 g) in ether (50 ml) under nitrogen. The mixture was heated under reflux for one hour and, after cooling, water and then a 20% aqueous solution of Rochelle's salt (potassium sodium tartrate tetrahydrate) (27 ml) and a 10% aqueous solution of sodium hydroxide (6 ml) added. The reaction mixture was stirred for one hour and then continuously extracted with ether during eighteen hours. The ether extract was dried and the ether removed to leave a solid from which 1-[1-(3,4-dichlorophenyl)cyclobutyl]ethylamine was separated by high pressure liquid chromatography. The product was identified by standard analytical techniques as the compound of Example 1 in the form of its free base.
