A solution of 6-chloro-3-nitropyridin-2-amine (0.175 M, 35 mL, 6.125 mmol) was added to (R)-piperidine-3-carboxylic acid, prepared during the previous step, followed by diisopropylethyl amine (2.275 mL, 12.25 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 for the next step without further purification.
