Page/Page column 7, (2008/12/04)
The invention relates to a method for preparation of aminoaryl- or aminoheteroarylboronic acids and esters and salts thereof in which an optionally substituted aminoaryl or aminoheteroaryl compound is protected at its nitrogen site via condensation with a carbonyl compound, subsequently metalated and converted with a suitable boron compound. Depending on the subsequent work-up and removal of the protective group, the corresponding boronic acid, the anhydride or the boronic acid ester thereof is obtained
