regioselective method for the SNAr amination of 2,4-dichloropyrimidine with oxazolidin-2-one and related weakly nucleophilic amines, using sodium sulfinate and tetrabutylammonium bromide as catalysts, is disclosed. This strategy facilitates the synthesis of various aminopyrimidines in a regio- and chemoselective manner. This approach was successfully used for the amination of various activated N-heteroaromatic
