In this letter a fast and useful parallel synthesis approach to 4-amino-2,6-dialkylamino-pyridines is described starting from commercially available 2,6-difluoro-3,5-dichloro-pyridine. Both symmetrical and unsymmetrical derivatives have been synthesized respectively in two or three steps in good yields. The method described is mild, adaptable to combinatorial purposes and applicable to a variety of amines. (C) 2002 Elsevier Science Ltd. All rights reserved.
