Reaction Steps

A solution of 2-chloro-5-nitropyridine (1.58 g, 10 mmol) and appropriate amine (20 mmol) in THF (60 mL) was heated for several hours at 60° C. The solvent was evaporated and water was then added to the reaction mixture. The product was isolated by filtration (piperidine, morpholine), or extracted from the water solution with ethyl acetate (1-methylpiperazine, 2-(2-hydroxyethylamino)ethanol)).
