Facile methods were developed to prepare a series of 6‐phenyl and 6‐alkyl‐2,4‐diaminopyrimidine derivatives. The pyrimidine ring of the final products was constructed by treatment of a 1,3‐dicarbonyl derivative with an amidine or guanidine. The 6‐phenyl‐pyrimidine derivatives were also prepared by Suzuki coupling reaction, using 2‐methylthio‐4,6‐dichloropyrimidine as the starting material. J. Heterocyclic
