Versuchsvorschrift

4-Chloro-2-fluoronitrobenzene (3.5 g) was dissolved in dry dimethylformamide (25 mL) and diisopropylethylamine (3.6 mL), and 1,1-dimethylethyl 4-amino-1-piperidinecarboxylate (4.2 g) were added at room temperature. The mixture was stirred at 80° C. for 1 h, then cooled to room temperature and water and ethyl acetate added. The organic layer was dried over MgSO4, filtered and evaporated, and the residue was purified by chromatography eluting with 10 to 25% ethyl acetate in hexane to afford the title compound, 6.8 g.
