FIELD: petrochemistry, namely, production of stabilization agents for caoutchouc, thermoelastic plastics and rubber. SUBSTANCE: method involves single step interaction of 2,6-dialkyl(diaryl or diaralkyl)phenol with amine and with carbon disulfide. The process is carried out in the presence of alcohol and aqueous solution of sodium hydroxide in the medium of aromatic hydrocarbon or aprotic solvent. N,N-tetralkyl methylene-bis-amine in which alkyl radical represents cycloalkyl, or aralkyl, or heterocyclic radical of amine type is used as mentioned above amine. EFFECT: simplified technology; pollution of environment is excluded. 2 cl, 1 tblS
