  Direct synthesis of Cbz-protected (2-amino)-6-(2-aminoethyl)pyridines

  摘要：

  A novel series of (2-amino)-6-(2-aminoethyl)pyridines were prepared by a convenient Suzuki-Miyaura coupling approach from 2-amino-6-bromopyridines. Benzyl vinylcarbamate was first treated with 9-BBN followed by aqueous NaOH and then the appropriate bromopyridine precursors were added into the mixture. The mixture was finally heated in presence of a palladium catalyst to provide the corresponding products in overall high yields. The procedure is extended to the preparation of related pyrazine and pyrimidine compounds as well as (2-amido)- and (2-alkoxy)-6-(2-aminoethyl)pyridines. (C) 2010 Elsevier Ltd. All rights reserved.
