摘要

Process for obtaining araliphatic amines of the general formula I ** (See formula) ** where R1 is a hydrogen or halogen atom, R2 a benzyl radical optionally substituted on the phenyl nucleus by a lower alkyl or alkoxy group, or a pentyl or cyclohexyl radical residue, and X represents a radical of hydrocarbon with 1 or 2 C atoms, characterized by a) reducing phenylacetone in the presence of amines of the general formula ** (See formula) ** where R1, R2 and X have the indicated meaning, or phenylacetone is transformed with amines of the formula II and the condensation products are subsequently reduced, or b) transforming an amine of the formula II with 1-phenyl-2-halogen-propane and respectively -propene and hydrogenating a double bond optionally present, or c) reducing, in the presence of 1-phenyl-2-amino-propane, aldehydes of the general formula III ** (See formula) ** where R1 and R2 have the indicated meaning and Y represents a carbon-carbon bond or the methylene group, or said aldehydes are transformed with 1-phenyl-2-amino-propane and the condensation products are subsequently reduced, or d) reduction in a manner known per se in the corresponding amides of carboxylic acid amides of the general formula IV ** (See formula) ** where R1, R2 and Y have the indicated meaning, or e) hydrogenating in a manner known per se compounds of the general formula V ** (See formula) ** where R1, R2 and Y have the indicated meaning, and optionally transformed with inorganic or organic acids, the basic compounds obtained in the corresponding salts.
