A solution of 6-chloro-3-nitropyridin-2-amine in N,N-dimethylformamide (70 mL, 12.25 mmol, 0.175M) was added to (R)-piperidine-3-carboxylic acid (12.25 mmol) followed by diisopropylethylamine (4.55 mL, 24.5 mmol). The reaction mixture was stirred at 80° C. for 16 h. The solvent was removed under reduced pressure to afford (R)-1-(6-amino-5-nitropyridin-2-yl)piperidine-3-carboxylic acid which was used without further purification.
