How is [3-(2-Hydroxyethyl)phenyl]boronic acid (CAS: 647853-32-5) typically synthesized?

[3-(2-Hydroxyethyl)phenyl]boronic acid is commonly synthesized via the Suzuki coupling reaction. The synthesis involves the reaction of phenyllithium with 2-hydroxyethyl boronic acid to form the boronic ester, which is then coupled with a halide or tosylate under palladium catalysis. This method provides good yields and high selectivity, making it a versatile route for this compound.
