Efficient regioselective preparation of monobromo and bromoiodo hydroxy pyridines from dibromoderivatives via bromine-lithium exchange

Annular dibromination of hydroxypyridines with NBS in acetonitrile followed by bromine-lithium exchange with RLi and subsequent trapping with H2O or I2 afforded monobromo and bromoiodo derivatives in a completely regioselective way. Iodination of bromo hydroxypyridines with NIS is totally regioselective.
