here essentially two general methods were followed in method i the methoxy tetralones were reacted with long chain alkyl or cycloalkyl amines to produce the substituted ketamines which in turn were hydrogenated to the final amine products in method ii the methoxy tetralones were reacted with hydroxyl amine to form the corresponding oximes the oximes were reacted with hydrogen to form the primary amino compound which compound in turn was reacted with a long chain alkyl or cycloalkyl aldehyde to form a schiff base the schiff base thus formed was then reduced to form the secondary amine compound containing the long chain alkyl or cycloalkyl radical the following examples illustrate preparation of typical compounds of the invention it is understood of course that these examples are merely illustrative and that the invention is not to be limited thereto here 0 1 mole 17 6 g of 5 hydroxy 1 tetralone was reacted with 0 1 mole 11 g of n hexylamine in the presence of 200 ml benzene solvent para toluene sulfonic acid was employed as a catalyst the benzene solution was refluxed for about 72 hours until the theoretical amount of 1 8 ml of water was collected in a water separator the benzene was then stripped to produce the corresponding n hexyl ketamine compound 0 1 mole of the ketamine in 200 ml ethanol was then hydrogenated with raney nickel catalyst 6 g after no additional uptake of hydrogen was noted the reaction was.
