Versuchsvorschrift

Piperidine (1.24 ml) was added to a solution of methyl 4-fluoro-3-nitrobenzoate (1.00 g) in DMF (20 ml) and the mixture was stirred at room temperature for 1 hour. The reaction mixture was diluted with ethyl acetate, sequentially washed with water and brine, and dried over anhydrous sodium sulfate. The filtrate was concentrated under reduced pressure and the residue was purified by silica gel column chromatography to obtain the title compound (1.50 g).
