PROCESS FOR THE PREPARATION OF HETEROCYCLIC TERTIARY ARALKYL AMINES

A process for the preparation of aralkylamines of the formula where R1 is hydrogen, an aliphatic hydrocarbon radical, a cycloaliphatic radical or alkoxy, R2, R3 and R4 are hydrogen or alkyl, X1, X2, X3 and X4 are hydrogen or alkyl, A is X5, X6, X7, X8, X9 and X10 are hydrogen or alkyl and n is 2, 3...

Summary:A process for the preparation of aralkylamines of the formula where R1 is hydrogen, an aliphatic hydrocarbon radical, a cycloaliphatic radical or alkoxy, R2, R3 and R4 are hydrogen or alkyl, X1, X2, X3 and X4 are hydrogen or alkyl, A is X5, X6, X7, X8, X9 and X10 are hydrogen or alkyl and n is 2, 3 or 4, by reacting a secondary amine with a carbonyl compound in the presence of hydrogen and of a hydrogenation catalyst which comprises palladium, mixed with zinc, cadmium, manganese and/or a rare earth metal oxide, on an inert carrier.
