ABSTRACT:
Novel anilines of the 2,6-dialkyl-4-dialkylaminomethylaniline type are prepared by reacting a secondary amine and an aldehyde with a primary aniline reactant having a free para position and substituents in both ortho positions in the presence of an acid catalyst, the amounts of amine and acid employed being at least equimolar with respect to the amount of aldehyde, and the reaction being conducted by adding the primary aniline reactant to a preformed mixture of the secondary amine, aldehyde, and acid.
