N-[2-methyl-5-(triazol-1-yl)phenyl]pyrimidin-2-amine as a Scaffold for the synthesis of inhibitors of Bcr-Abl

N-[2-Methyl-5-(triazol-1-yl)phenyl]pyrimidin-2-amine derivatives were synthesized and evaluated invitro for their potential use as inhibitors of Bcr-Abl. The design is based on the bioisosterism between the 1,2,3-triazole ring and the amide group. The synthesis involves a copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) as the key step, with the exclusive production of anti-(1,4)-triazole derivatives. One of the compounds obtained shows general activity similar to that of imatinib; in particular, it was observed to be more effective in decreasing the fundamental function of cdc25A phosphatases in the K-562 cell line.
