摘要

Heteroaromatic amines are present in several biologically active compounds in addition to being versatile building blocks.[1, 2] We are particularly interested in the synthesis of aminopyridines analogous to prazosin for a study on the mechanism of action of Transport-P ligands.[3–5] Aminopyridines are usually prepared from halopyridines and amines by nucleophilic aromatic substitution (SNAr)[6] or by transition metal-mediated protocols like ...
