A mild and efficient Pd-catalyzed coupling of amides with 2-chloropyrimidines is described. The use of bidentate phosphines, such as Xantphos (7), as supporting ligands was found to be crucial for providing high yields of 2-(N-acylamino)pyrimidine coupling products 1. (C) 2010 Elsevier Ltd.

C2-Selective, Functional-Group-Divergent Amination of Pyrimidines by Enthalpy-Controlled Nucleophilic Functionalization
Synthesis of heteroaryl amines has been an important topic in organic chemistry because of their importance in small-molecule discovery. In particular, 2-aminopyrimidines represent a highlyprivilegedstructuralmotif that is prevalent in bioactive molecules, but a general strategy to introduce the pyrimidine C2–N bonds via direct functionalization is elusive. Here we describe a synthetic platform
