Reaction Steps

To a slurry of 2-chloro-5-nitropyridine (10 g, 63.1 mmol) in EtOH (100 mL) at room temperature was added pyrrolidine (15.72 mL, 189 mmol) and the mixture was heated at 70° C. for 18 hours. The cooled solution was concentrated in vacuo and the residue partitioned between CH2Cl2 and 1 M NaOH. The organic layer was dried (Na2SO4), filtered and solvent removed in vacuo to give title compound (9.52 g, 78%). MS (ESI) m/z 194 (M+H)+.
