The invention relates to an improved method for synthesizing L-thyroxine sodium. The improved method includes the steps that 3,5-diiodomethane-L-tyrosine is used as a raw material, and then subjectedto a copper complex reaction, a coupling reaction, an acid hydrolysis reaction, an iodine generation reaction and a salt forming reaction to obtained the L-thyroxine sodium. According to the improvedmethod for synthesizing the L-thyroxine sodium, the yield of the L-thyroxine sodium can be improved, the product cost is lowered, and industrialization is convenient.
