FIELD: organic chemistry, organic synthesis, chemical technology.
SUBSTANCE: invention describes a method for synthesis of di-[(6-benzyl-4,2,6-thiadiazolidine-2-yl)methyl]sulfide of the general formula (1): 
. Method involves interaction of formaldehyde aqueous solution saturated with hydrogen sulfide with benzyl hydrazine in the mole ratio benzyl hydrazine : formaldehyde : hydrogen sulfide = 1:3:2, respectively, at temperature 0°C and stirring the mixture for 3 h. Invention provides preparing the end product with high regioselectivity.
EFFECT: improved method of synthesis.
