Abstract
A convenient synthesis of 4-amino-7-(dialkylamino)pyrido[2,3-d]pyrimidines via cyclization of functionalized pyridines is reported. The preparation of the starting pyridines from 3-amino-3-(dialkylaraino)propene-nitriles and ethoxymethylenemalononitrile is described.Items in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
