This disclosure concerns compounds and a method for modulating the activity of calcium ion channels, including Ca2+-induced (or Ca2+-activated) calcium release channels and conformationally coupled calcium release channels such as ryanodine receptors. Some of the compounds have a structure according to formula I, or a stereoisomer, tautomer, hydrate, solvate, prodrug, or pharmaceutically acceptable salt thereof.
Synthesis of 3-Aminoimidazo[1,2-a]pyridines from α-Aminopyridinyl Amides

3-Aminoimidazo[1,2-a]pyridines are rapidly synthesized via a facile and mild cyclodehydration-aromatization reaction starting from readily available amides. The cyclodehydration step is mediated by the activation of N-Boc-protected 2-aminopyridine-containing amides by triflic anhydride (Tf2O) in the presence of 2-methoxypyridine (2-MeO-Py). Subsequently, the addition of K2CO3 in THF ensured a clean deprotection-aromatization sequence to afford the desired heterocycle. A wide variety of functional groups and substitution patterns were tolerated under the optimized procedure, and good to excellent yields were obtained for the fused bicyclic 3-aza-heterocycles. In addition, the reaction was found to be scalable to gram-scale and could be performed with unprotected acyclic amide precursors. We also found that the resulting products were valuable intermediates for both Pd- and Ru-catalyzed C-H arylation reactions, allowing for the elaboration to diversely functionalized building blocks.
