Abstract A simple and efficient synthesis of 3,5‐dibromo‐O‐methyl‐L‐tyrosine is described by directbromination of commercial O‐methyl‐L‐tyrosine with bromine in aqueous hydrochloric acid. MO calculations are presented to explain a difference in the degree of substitution of O‐methyl‐L‐tyrosine in different solvents.
