Reaction Steps

2-Chloro-5-methyl-4-nitropyridine N-oxide (200 mg, 1.06 mmol, 1.0 equivalent) was dissolved in ethanol (1.5 mL). (S)-2-Aminobutanol (284 mg, 3.2 mmol, 3.0 equivalent) was then added and the resulting mixture was refluxed for 16 hours. The crude solution was then purified by reversed phase HPLC (acetonitrile/water/TFA) to afford the title compound as a brown solid (146 mg, 0.61 mmol, Rt(min) 3.787; FIA ES+ 241.8, ES− not observed).
