FIELD: medicine.
SUBSTANCE: invention refers to a method for producing thyroid hormones of formula 
The method involves carrying out a reaction of a compound of formula 
with an iodinating agent containing NaI and I2 in the presence of aliphatic amine to produce a disodium derivative of formula II as a raw material. The produced alcohol water alkaline solution of the compound of formula II having pH at least 11 is heated to a temperature of 40°C to 80°C, cooled down to a temperature of 5°C to 20°C, and the compound II is recovered as a pure solid material.
EFFECT: presented method enables the one-stage production of high-yield and high-purity disodium salt II.
