, (2008/06/13)
Aniline derivatives of the formula STR1 wherein R is hydrogen, C1 -C4 -alkyl or C1 -C4 -alkyl substituted by C1 -C2 -alkoxy are produced by reacting a N-(3-pent-2-enyl)-derivative of morpholine, piperidine or pyrrolidine with acrolein in the presence of an inert, aprotic solvent or in the absence of a solvent and heating the reaction product obtained to 100°-400° C. in the presence of a hydrogen-transfer catalyst and in the presence of an amine of the formula R--NH2, wherein R has the meaning given above.
