The synthesis and SAR of a series of 6-chloro-4-fluoroalkylamino-2-heteroaryl-5- (substituted) phenylpyrimidines as anti-cancer agents are described. This series of 2- heteroarylpyrimidines was developed by modifying a series of anti-tumor [1, 2, 4] triazolo [1, 5-a] pyrimidines and 2-cyanoaminopyrimidines we reported earlier.
