FIELD: chemistry.
SUBSTANCE: invention relates to field of organic chemistry, namely, to method of obtaining N,N,N1,N1-tetrasubstituted di[4-(aminomethylsulfanyl)]phenyl ethers of general formula (1): 
, which lies in the following: di-(4-sulfanyl)phenyl ether is subjected to interaction with water formaldehyde and secondary amines (N-benzylanilin, piperidine, morpholine) in presence of catalyst samarium nitrate crystallohydrate Sm(NO3)3·6H2O with mole ratio di-(4-sulfanyl)phenyl ether : CH2O : RR'NH : Sm(NO3)2·6H2O - 10 : 20 : 20 : (0.3-0.7), at room temperature (20°C) and atmospheric pressure for 0.5-1.5 h.
EFFECT: elaborated is method of obtaining said phenyl ethers, which can be applied as novel modified means for protection of plants against root rots and means, increasing productivity of crops.
