A process for preparing amines of the formula I (I) where R1,R2,R3,R4,R5,R6 are hydrogen, C1- to C20-alkyl, C2- to C20-alkenyl, C2- to C20-alkynyl, C3- to C20-cycloalknyl, C4- to C20-alkyl-cycloalkyl, C4- to C20-cycloalkyl-alkyl, aryl, C7- to C20-alkylaryl or C7- to C20-aralkyl, R1 and R2 jointly are a saturated or unsaturated C3- to C9-alkylene divalent chain and R3or R5 are C21- to C200-alkyl, C21- to C200-alkenyl or jointly are a C2- to C12-alkylene divalent chain, by reacting olefins of the formula II (II) where R3, R4, R5 and R6 have the abovementioned meanings, with ammonia or primary or secondary amines of the formula III (III) where R1 and R2 have abovementioned meanings, at from 200 DEG to 350 DEG C. and from 100 to 300 bar in the presence of a heterogeneous catalyst, by using zeolites of the MCM-49 or MCM-56 type as the heterogeneous catalyst.
