A mixture of 1,2-difluoro-3-nitrobenzene (2.38 g, 0.015 mmol), (R)-tert-butyl piperidin-3-ylcarbamate (3.0 g, 0.015 mmol) and N,N-diisopropylethylamine (5.2 ml, 0.030 mmol) was heated in acetonitrile (20 mL) at 80° C. overnight. The solvents were removed in vacuo, and chromatographic purification (ethyl acetate-hexanes) of the residue gave a nitropiperidine as orange oil (3.7 g, 72%).
