Palladium-catalyzed amidation of 2-chloropyrimidines
摘要:
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.
