The invention discloses a modified synthesis method of oxidative phosphorylation-L-tyrosine, and belongs to the field of organic chemistry. L-tyrosine and phosphorus pentoxide are reacted in 85% strong phosphoric acid, a molar ratio of the L-tyrosine to the phosphorus pentoxide to the strong phosphoric acid is 1 to (1.5 to 3) to (4 to 8), and the modified synthesis method of the oxidative phosphorylation-L-tyrosine further comprises post-treatment, wherein post-treatment comprises the following steps that after the reaction is completed, water is added for quenching reaction, a system pH is adjusted to be 2.5, and solid precipitates. A technology route adopted in the modified synthesis method of the oxidative phosphorylation-L-tyrosine is simple and short, post-treatment is simple and easyto implement, raw materials are cheap and easy to get, reaction conditions are mild, the yield is high, and the oxidative phosphorylation-L-tyrosine is suitable for industrial large-scale production. 本发明公开了种氧磷酸-L-酪氨酸的改进合成方法，
