Na2S2O4: A versatile reagent for the one-pot synthesis of 2-aryl-1h-imidazo[4,5-c]pyridines from 4-amino-3- nitropyridine and aldehydes via reductive cyclization

Dubey,Chowdary,Ramesh,Reddy, P. V. V. Prasada

experimental part, p. 697 - 708 (2011/03/19)

A highly efficient and versatile method for the synthesis of 2-aryl-1H-imidazo[4,5-c]pyridines 3 was achieved in one step via reductive cyclization of 4-amino-3-nitro-pyridines 4 with aromatic aldehydes in the presence of Na2S2O
