Synthesis and biological evaluation of N-arylbenzo [b] thieno [3, 2-d] pyrimidin-4-amines and their pyrido and pyrazino analogues as Ser/Thr kinase inhibitors
A useful and rapid access to libraries of N-arylbenzo [b] thieno [3, 2-d] pyrimidin-4-amines and their pyrido and pyrazino analogues was designed and optimized for the first time via microwave-accelerated condensation and Dimroth rearrangement of the starting anilines with N′-(2-cyanoaryl)-N, N-dimethylformimidamides obtained by reaction of thiophene precursors with dimethylformamide dimethylacetal. The inhibitory potency of the final ...
