The convenient preparation of three imidazo[1,2-a]pyridine-2-carboxamide intermediates is reported through known Strecker–Ugi type multicomponent reactions, Tschitschibabin type condensations, and further synthetic sequences. The derivatives were then efficiently converted to novel 4-chloro-2-(trifluoromethyl)pyrido[1,2-e]purines by their original reactions with 2,2,2-trifluoroacetamide, followed by subsequent dehydroxychlorination reactions. These compounds were cross-coupled under microwave irradiation through SuzukiMiyaura and Sonogashira palladium(0) catalysis to various aromatic and alkynyl reagents, thus providing the related C-4 substituted pyrido[1,2-e]purines of biological interest in good yields.

A series of imidazolepyridine derivatives were designed and synthesized according to the established docking studies. The imidazopyridine derivatives were found to have good potency and physical-chemical properties. Several highly potent compounds such as 8ji, 8jl, and 8jm were identified with single nanomolar activities. The most potent compound 8jm showed an IC50 of 3 nM, lower microsome clearance and no CYP inhibition. The profile of 8jm appeared to be superior to BMS433771, and supported further optimization.
