Li, Chaomin published the artcileRapid construction of imidazopyridines from ortho-haloaminopyridines, Computed Properties of 39856-58-1, the publication is Tetrahedron Letters (2016), 57(25), 2708-2712, database is CAplus.
A practical strategy for the preparation of imidazopyridine derivatives from ortho-haloaminopyridines using a two-step C-N coupling/cyclization reaction sequence was developed. This procedure provides rapid and efficient access to many medicinally interesting imidazopyridine compounds and related imidazopyrazine/purine heterocycles.
