FIELD: organic chemistry. SUBSTANCE: method is carried out by interaction of dimethyl amine, 2,6-di-tert-butyl phenol and aqueous solution of formaldehyde, the two latter reagents being fed by counterflow. Said process takes place at 100-110 C in the presence of SSS as catalyst. Mass ratio of 2,6-di-tert-butyl benzene, catalyst and solvent is 1:1.5-1.8:0.0003-0.0016 respectively. EFFECT: increases conversion, improves quality of desired product. 4 tbl
