A practical and convenient one–pot procedure for reductive ortho–amination of pyridyl N-oxides is described, using potassium phthalimide and tosyl chloride followed by hydrolysis. The scope and applicability of the reaction was demonstrated, providing various mono- and di-aminated products in moderate to excellent yields.
