Novel pyrimidine derivatives were prepared from the reaction of 2-substituted 1,3-bis(dimethylamino)-trimethinium salts with thiourea or guanidine in the presence of ethyl-diisopropylamine in ethanol at reflux, and also some 5-substituted pyrimidine-2-thi

Suzuki reactions have been used successfully to effect cross-coupling of 5-halopyrimidines with 4-chlorobenzeneboronic acid and 2,4-diamino-5-(4-chloro-3-halo)-6-ethylpyrimidines with 4-methoxybenzeneboronic acid. The antimalarial drug pyrimethamine has been prepared by coupling 2,4-diamino-6-ethyl-5-iodopyrimidine with 4-chlorobenzeneboronic acid.
