Several derivatives of N, N-bis (3, 5-di-tert-butyl-4-hydroxybenzyl)-N-alkylamines were isolated in the reduction of the imines obtained from 3, 5-di-tert-butyl-4- hydroxylbenzaldehyde and primary amines. Experimental results showed that they were transformed from the corresponding 2, 6-di-tert-butyl-4-alkylaminomethylphenols.
