A process for the preparation of 2,6-dialkylaniline which comprises the reaction of a 1-nitroalkene with a 1,3-alkadiene to form a dialkyl nitrocyclohexene adduct and subsequent reaction of the resulting adduct with hydrogen in the presence of a hydrogenation catalyst to form the corresponding dialkylcyclohexyl amine, followed by dehydrogenation with aqueous ammonia in the presence of a dehydrogenation catalyst.
