Versuchsvorschrift

To a 0° C. EtOAc (150 mL) solution of 3-fluoro-4-nitrobenzamide (4.85 g, 26.4 mmol) and Et3N (5.34 g, 52.8 mmol) was added dropwise a CH2Cl2 (50 mL) solution of 1,1,1-trichloroacetyl chloride (5.28 g, 29.04 mmol). The reaction was complete in 2 h (TLC, 1:1 hexane:EtOAc), then it was washed with 1N HCl, dried (MgSO4) and evaporated to give 4.1 g of the corresponding nitrile.
